ontinuous-wave laser operation of bulk Er:Yb:phosphate glass pumped at 980 nm by an InGaAs index-guided diode laser has been achieved for the first time to our knowledge, with 2 mW of output power obtained at 1.54 microm. To optimize pumping conditions and to investigate the effects of pump wavelength, the Er(3+):Yb(3+) glass disk has also been pumped by a Ti:Al(2)O(3) laser at 960 and 980 nm, and we obtained high output power (70 mW) and the highest slope efficiency (21% for 980-nm pumping) reported to date for a bulk Er:glass laser.
据我们所知,首次实现了由InGaAs折射率导引二极管激光器在980 nm波长泵浦的块状铒镱磷酸盐玻璃的连续波激光运转,在1.54微米波长处获得了2毫瓦的输出功率。为了优化泵浦条件并研究泵浦波长的影响,还用钛宝石激光器在960和980 nm波长对铒镱玻璃盘进行了泵浦,我们获得了高输出功率(70毫瓦)以及迄今为止块状铒玻璃激光器所报道的最高斜率效率(980 nm泵浦时为21%)。
