【Abstract】 An investigation on a σ polarization Ti∶sapphire laser end pumped a cut Nd∶ YVO 4 microchip laser was reported, which can compensate the thermally induced lensing effect. The laser operated in π polarization at single transverse mode with a very low threshold of 2 mW and a high optical conversion efficiency of 50.7%. Under 880 mW pumping power, an output laser power 440 mW has been obtained. At the meantime, the evolution of longitudinal modes in terms of the pumping power was also studied, and the temporal spectrum taken indicated that the 1.064 μm laser output had relatively high stability when pumped by σ polarization Ti∶sapphire laser.更多还原
