用两个激光二极管堆叠双端泵浦掺2% Tm3+的LiYF4（Tm:YLF）板。泵送容积具有矩形截面。在mx2≈199和my2≈1.7的入射泵浦功率为554 W的情况下，Tm:YLF激光器在1912 nm处产生148 W的连续波输出。相对于入射泵浦功率的斜率效率为32.6%，光对光效率为26.7%。
A 2% Tm3+-doped LiYF4(Tm:YLF) slab is double-end-pumped by two laser diode stacks. The pumped volume has a rectangular cross section. The Tm:YLF laser produced 148 W of continuos-wave output at 1912 nm in a beam withMx2≈199 andMy2≈1.7 for 554 W of incident pump power. The slope efficiency with respect to the incident pump power was 32.6%, and the optical-to-optical efficiency was 26.7%.
