摘要：

The　output　power　of　linearly　polarized　Nd:YAG　lasers　is　typically　limited　by　thermally　induced　birefringence,　which　causes　depolarization.　However,　this　effect　can　be　reduced　by　use　of　crystals　which　are　cut　in　[100]-direction,　instead　of　the　common　[111]-direction.　In　this　paper,　crystals　cut　in　[111]-　and　[100]-directions　are　pumped　by　laser　diodes.　A　comparison　of　the　output　power　of　linearly　polarized　laser　between　two　crystals　is　presented.　The　experiments　demonstrate　that　the　depolarization　can　be　reduced　and　the　output　power　can　be　improved　through　using　a　[100]-cut　Nd:YAG　crystal　instead　of　a　[111]-cut　crystal.
