Diode-pumped laser action of a new crystal yb3+:Lu2Si207 (LPS) is demonstrated for the first time to our knowledge. An output power of 2.22 W at 1070 nm and a slope efficiency of 34.7% were achieved with a 5 at.-% Yb: LPS sample. The tuning can cover the range form 1034 to 1080 nm. 相似文献

A compact high-power picosecond regenerative amplifier based on continuous wave(CW) diode sidepumped Nd:YAG is demonstrated.Average power of 8.8 W is achieved at a repetition rate of 5 kHz at a wavelength of 1 064 nm with a pulse duration of 28 ps,corresponding to a pulse energy of 1.76 mJ and a peak power of 62.9 MW.The beam quality is close to the di?raction limit with Mx2 = 1.24,My2 = 1.03.To the best of our knowledge,this is the highest pulse energy obtained from a CW diode pumped Nd:YAG picosecond regenerative amplifier. 相似文献

An efficient high-power diode-pumped femtosecond Yb:KGW laser is repored. Through optimization of energy density by semiconductor saturable absorber mirror, output power achieved 2.4 W with pulse duration of 350 fs and repetition rate of 53 MHz at a pump power of 12.5 W, corresponding to an optical-to-optical efficiency of 19.2%. We believe that it is the highest optical-to-optical efficiency for single-diode-pumped bulk Yb:KGW femtosecond lasers to date. 相似文献
