It is reported that efficient continuous-wave (CW) self-frequency-doubling green laser at 530 nm performed with a diode-pumped
Nd3+:YCa4O(BO3)3 (Nd:YCOB) laser. With a diode pump power of 14.3 W, TEM00 mode green laser at 530 nm of 1.07 W is obtained. At the output power level of 1.07 mW, the output stability is better than
5%. The beam quality M2 value is about 1.37. To the best of our knowledge, this is the highest power laser at 530 nm generated by self-frequency

diode-pumped Nd:YAG laser at 1338 nm. With 16.9 W of diode pump power and the frequency-doubling crystal KTiOPO4 (KTP), a maximum output power of 582 mW in the red spectral range at 669 nm has been achieved, corresponding to an optical-to-optical
conversion efficiency of 3.4%; the output power stability over 4 h is better than 3.6%. To the best of our knowledge, this

Nd:Ca4YO(BO3)3 (Nd:YCOB) crystal was grown by the Czochralski method, and its structure was measured by using a four circle X-ray diffractometer. The transparent spectrum from 200 to 2600 nm was measured at room temperature. The fluorescence spectrum near 1.06 μm showed that the main emission wavelength of Nd:YCOB crystal was centered at 1060.8 nm. Laser output at 1.06 μm has been demonstrated when it was pumped by a Ti:sapphire laser at the wavelength of 794 nm, the highest output power was 68 mW under pumping power of 311 mW, the pumping threshold was 163 mW and slope efficiency was 46.9%. The self-frequency doubled green light has been observed when it was pumped by a Ti:sapphire or a laser diode (LD). A 14.5 mm Nd:YCOB crystal sample cut at (θ, φ)=(90°, 33°) was used for type I second-frequency generation (SHG) of the 1.06 μm laser pulse. The SHG conversion efficiency was 22%. 相似文献
