The multiple pump sources are used to increase the output power of single fiber laser , and the two dimensions arrange of fiber laser array increases the number of combining fibers 利用多泵浦源提高单根光纤激光器的输出功率,利用二维光纤激光阵列排列增加参与组束的光纤数目。
The first ytterbium - doped yttrium - aluminum garnet ( yb : yag ) laser action was reported back in 1965 using a lamp - pumped rod at 77 k . because of poor spectral overlap of the lamp with the the trivalent ytterbium ion ( yb3 + ) absorption band , the efficiency was very low . lamp - pumped nd : yag lasers fared better due to the multiple pump bands of neodymium 但yb3 +离子的泵浦吸收带与闪光灯光谱匹配很差,导致其激光效率很低;而nd : yag的激活离子( nd3 + )有多个泵浦带与闪光灯光谱匹配,较好适应了灯泵浦的需要,长期占据了固体激光器的主导地位。
