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 利用多泵浦源提高單根光纖激光器的輸出功率,利用二維光纖激光陣列排列增加參與組束的光纖數(shù)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 +離子的泵浦吸收帶與閃光燈光譜匹配很差,導(dǎo)致其激光效率很低;而nd : yag的激活離子( nd3 + )有多個(gè)泵浦帶與閃光燈光譜匹配,較好適應(yīng)了燈泵浦的需要,長期占據(jù)了固體激光器的主導(dǎo)地位。
