We report for the first time a coherent orange-red radiation at 616 nm by intracavity sum-frequency generation of the 1080
and 1433 nm laser-lines of two Nd:YAP lasers. Orange-red laser is obtained by using a doubly linear resonator, type-II critical
phase matching KTiOPO4 (KTP) crystal sum-frequency mixing. With a total diode pump power of 26.5 W (8.7 W pump power for 1080 nm Nd:YAP laser and
17.8 W pump power for 1433 nm Nd:YAP laser), TEM00 mode orange-red laser at 616 nm of 127 mW is obtained. The power stability
in 30 min is better than 3.3%. 相似文献

We present for the first time a Nd:YVO4 laser emitting at 1064 nm intracavity pumped by a 916 nm diode-pumped Nd:LuVO4 laser. A 809 nm laser diode is used to pump the Nd:LuVO4 crystal emitting at 916 nm, a Nd:YVO4 laser crystal was pumped at 916 nm and lased at 1064 nm. Intracavity sum-frequency mixing at 916 and 1064 nm was then realized
in a LiB3O6 (LBO) crystal to reach the blue range. We obtained a continuous-wave output power of 216 mW at 492 nm under 19.6 W of incident
pump power at 809 nm. 相似文献

A design of laser-diode array (LDA) end-pumped Nd:YVO4 laser that generates simultaneous laser action at wavelengths 1064 and 1342 nm is presented. Using type-I critical phase matching (CPM) BiB3O6, 593.5 nm continuous-wave (cw) Orange-yellow laser is obtained by 1064 nm and 1342 nm in an intra-cavity sum-frequency mixing. The maximum laser output power of 3.62 W is obtained when an incident pump laser of 27.5 W is used. The optical-to-optical conversion is up to 13.2%. To the best of our knowledge, this is the highest conversion efficiency at 593.5 nm in an intra-cavity sum-frequency Nd:YVO4 laser. 相似文献

We report for the first time a coherent radiation at 554.7 nm by intracavity sum-frequency generation of 946 nm Nd:YAG laser and 1341 nm Nd:YAP laser. Yellow-green laser is obtained by using a doubly folded cavity, type-II critical phase matching KTP crystal sum-frequency mixing. With total pump power of 36.1 W (17.8 W pump power for 1341 nm Nd:YAP laser and 18.3 W pump power for 946 nm Nd:YAG laser), TEM00 mode yellow-green laser at 554.7 nm of 1.43 W is obtained. 相似文献

We present for the first time a dual-wavelength laser operation at 1064 and 914 nm in two NdYVO4 crystals. A 879 nm laser diode is used to pump the first Nd:YVO4 crystal emitting at 914 nm, and the second Nd:YVO4 laser emitting at 1064 nm intracavity pumped at 914 nm. A total output power of 4.28 W at the two fundamental wavelengths
was achieved at the absorbed pump power of 13.8 W. The M2 values for 914 and 1064 nm lights at the maximum output power were found to be around 1.3 and 1.1, respectively. 相似文献

We report a laser architecture to obtain continuous-wave blue radiation at 488 nm. A 808 nm diodepumped the Nd:YVO4 crystal emitting at 914 nm. A part of the pump power was then absorbed by the Nd:YVO4 crystal. The remaining was used to pump the Nd:YLF crystal emitting at 1047 nm. Intracavity sum-frequency mixing at 914 and
1047 nm was then realized in a LBO crystal to reach the blue radiation. We obtained a continuous-wave output power of 514
mW at 488 nm with a pump laser diode emitting 19.6 W at 808 nm. 相似文献

A design of LD-pumped Nd:YVO4 laser that generates simultaneous laser action at wavelengths 1064 and 1342 nm by optimizing film design is presented. An optimized continuous-wave (cw) yellow laser at 593.5 nm in room temperature is obtained for the first time. Using type-I critical phase-matching (CPM)LBO crystal, a yellow laser at 593.5 nm is obtained by 1064 and 1342 nm intracavity sum-frequency mixing. The maximum laser output power of 85 mW is obtained when an incident pump laser of 1.8 W is used. The optical-to-optical conversion is up to 4.7%, and the power stability in 24 h is better than ±2.8%. 相似文献

An all-solid-state single-longitudinal-mode (SLM) laser at 500.8 nm with 830 mW output power has been demonstrated for the
first time. By using a new resonator for doubly resonant, Nd:GdVO4 and Nd:YAG were pumped by two laser diode arrays coupled by optical fiber, respectively. In the two sub-cavities, SLM wavelengths
of 1064 and 946 nm were induced by using the twisted-mode technique and then mixed into SLM 500.8 nm laser with sum-frequency
technology. The SLM 500.8 nm laser output of 830 mW was obtained at the incident pump power of 20 W for Nd:GdVO4 and 23 W for Nd:YAG. The experimental results showed that the intracavity sum-frequency mixing by twisted-mode technique
is an effective method for SLM 500.8 nm laser. 相似文献

In this paper, a high-power continuous-wave deep blue laser at 447 nm with intracavity tripling was achieved. The deep blue laser at 447 nm is obtained by using a doubly cavity, and type-II critical phase matching KTP crystal for intracavity sum-frequency mixing. Through designing of the cavity, the optimum matching of modes and gains for the two wavelengths was obtained. With incident pump power of 30 W for the Nd:YVO4 crystal and 16 W for the other Nd:YVO4 crystal, the deep blue laser output of 3.5 W at 447 nm with TEM00 mode was obtained, the beam quality M2 value was equal to 1.8 in both horizontal and vertical directions at the maximum output power, and the power stability is better than 3% at the maximum output power during half an hour. The experimental results show that the intracavity sum-frequency mixing by doubly resonant is an effective method for high-power blue laser. 相似文献

output power of 1.79 W was achieved at the incident pump power of 18.2 W. Furthermore, intracavity sum-frequency mixing at
914 and 1342 nm was then realized in a LBO crystal to reach the yellow-green range. We obtained a total CW output power of
212 mW at 544 nm. 相似文献

By using a piece of single-walled carbon nanotube saturable absorber, the performance of the passively Q-switched composite
Nd:YVO4 laser has been demonstrated for the first time. The maximum average output power and the shortest pulse width are 1220 mW
and 103 ns at the incident pump power of 5.04 W for a 10% transmission of the output coupler. The highest pulse repetition
rate of 415.6 kHz and the largest single-pulse energy of 2.94 μJ are also obtained. The composite Nd:YVO4 crystal has more excellent laser performance than the normal Nd:YVO4 crystal at 1064 nm. 相似文献

We report a laser architecture to obtain continuous-wave (cw) blue radiation at 462 nm. A 808 nm diode-pumped the Nd:YVO4 crystal emitting at 914 nm. A part of the pump power was then absorbed by the Nd:YVO4 crystal. The remaining was used to pump the Nd:CNGG crystal emitting at 935 nm. Intracavity sum-frequency mixing at 914 and 935 nm was then realized in a LiB3O5 (LBO) crystal to reach the blue radiation. We obtained a continuous-wave output power of 892 mW at 462 nm with a pump laser diode emitting 18.4 W at 808 nm. 相似文献

A sum-frequency yellow-green laser at 554.9 nm is reported by this paper, 946 nm wavelength is obtained from 4F3/2-4I9/2 transition in Nd:YAG and 1342 nm wavelength is obtained from 4F3/2-4I13/2 transition in Nd:YVO4. Using a doubly folded-cavity type-II critical phase matching KTP crystal intra cavity to make 946 nm laser from Nd:YAG and 1342 nm laser from Nd:YVO4 frequency summed, with incident pumped power of 30 W in Nd:YAG and 20 W in Nd:YVO4, TEM00 mode yellow-green laser at 554.9 nm at 1.15 W is obtained and its M2 factor is less than 1.22. The experimental results show that the Nd:YAG and Nd:YVO4 crystals intra-cavity sum-frequency mixing is an effective method for yellow-green laser and it can be applied to other two laser crystals to obtain more all-solid-state lasers with different wavelengths. 相似文献

A compact and efficient 593.5 nm orange-yellow laser is realized using doubly resonant intracavity sum frequency mixing. Two Nd: YVO4 crystals are employed as the gain crystals. In two sub-cavities, 1064 nm radiation from one Nd: YVO4 and 1342 nm radiation from the other Nd: YVO4 are mixed to generate 593.5 nm orange-yellow laser. In the overlapping of the two cavities, sum frequency mixing is achieved in a type I critical phase matching (CPM) LBO crystal. An output power of 3.2 W at the wavelength of 593.5 nm is obtained with total incident pump power of 38 W. The optical to optical conversion efficiency is up to 8.4% and the stability of the output power is better than 2.48% in 8 h. To the best knowledge, this it the highest watt-level laser at 593.5 nm generated by diode end pump all-solid-state technology. 相似文献
