A Yb:YAG disk laser with V-shaped stable resonator and active-mirror configuration,end-pumped by a 940-nm InGaAs laser diode array,is demonstrated.Performances and optimization of the disk laser at low temperature over a range of 130-200 K are investigated theoretically and experimentally.Laser output energy of 1.46 J/pulse operating at 10-Hz repetition rate is obtained with the optimum output coupler transmission of 30%,and the corresponding optical-to-optical efficiency is 48.7%. 相似文献

A 1.5 J Nd:LuAG ceramic active mirror laser amplifier with a high beam quality is demonstrated in which a 0.8%(atomic fraction)Nd-doped Nd:LuAG ceramic disk with a diameter of 64 mm and a thickness of 5.5 mm is used as a laser gain medium.A maximum single-pass small-signal gain of 2.59 is measured when the pump energy is 11.5 J,with an injected seed energy of 0.4 J;a maximum output energy of 1.5 J is obtained at the repetition rate of 10 Hz.A far-field beam spot 1.25 times the diffraction limit(DL)is achieved by using a stimulated Brillouin scattering phase conjugation mirror(SBS-PCM)for wavefront correction. 相似文献

<正>We investigate a theoretical model to accurately predict the output performances of slab laser amplifiers, which is one of the key issues in the study of space-based lasers.The realistic absorbed pump energy density,which induces nonuniformity of stored energy density in the laser medium,is introduced into the model.Using this model,the amplification performances of two space-based laser amplifiers with different pump configurations are compared.The results indicate that the bounce-pumped amplifier(BPA) achieves much higher output energy and efficiency compared with the side-pumped amplifier(SPA);it is also more suitable for space-based lasers. 相似文献
