Study on the stiction effect of indium module on the microminiaturized diode pump solid state laser

The effect of indium module on the microminiaturized diode pump solid state laser was researched via pre-stress experiments and the effects experiments of pump heat and impacting. Under the effect of pre-stress, the coarse edges of the part module were embedded in the indium module, which increased the stiction. The stietion effect was evident in the indium module samples undergoing power-current-temperature capability （P-I-T） test. The pump heat caused part of the indium modules to adhere to pump crystals, which increased the stiction. Dynamic recovery appeared in the indium module that underwent 2.5 m impacting and the P-I-T test＇s pump heating, which reinforced the coarse edges of the part module embedded in the indium module and increased the stiction. The results indicate that the impact resistance of the pump crystals and the indium module mierominiaturized pump solid state laser is enhanced.
