摘要	A solid-state laser having a rod of active material optically pumped along the side of the rod by an array of diode lasers. Beam shaping elements, such as Brewster angle facets on the end of the laser rod, cause the laser beam to assume a generally elliptical shape within the rod with the long axis of the ellipse aligned with the irradiation angle of the diode lasers. However, the beam is circularly shaped outside the rod. Preferably, the laser rod is held within an optical cavity formed within a cooling block which both cools the rod and reflects pump light back into the rod. The diode lasers irradiate the rod through a linear slit in the cooling block. Also, preferably, a slab-shaped optical waveguide is placed within the slit to guide the light from the diode lasers to the side of the laser rod.
其他摘要	一种固态激光器，其具有通过二极管激光器阵列沿杆的侧面光学泵浦的活性材料棒。光束整形元件，例如激光棒端部上的布鲁斯特角小平面，使激光束在杆内呈现大致椭圆形状，椭圆的长轴与二极管激光器的照射角度对齐。然而，梁在杆外部是圆形的。优选地，激光棒保持在形成于冷却块内的光学腔内，该冷却块既冷却杆又将泵浦光反射回杆中。二极管激光器通过冷却块中的线性狭缝照射杆。而且，优选地，将板状光波导放置在狭缝内，以将来自二极管激光器的光引导到激光棒的侧面。
