研究了钕硅酸盐玻璃与单壁碳纳米管（SWCNTs-SAM）和半导体可饱和吸收镜（SESAMs）的锁模操作。SWCNT-SAM锁模已被优化，在掺钕体激光器的第一次，在1070 nm处产生99-fs的脉冲。作为比较，通过使用SESAM代替SWCNT-SAM，实现了短至87 fs的脉冲和30 nm的调谐范围。采用200 mW单模半导体激光器作为泵浦源，获得了高效率、低阈值的激光器。优化后的低功率泵浦装置在连续波区获得了46.5%的斜率效率。
The mode-locked operation of Nd:silicate glass with both single-walled carbon nanotubes (SWCNTs-SAM) and semiconductor saturable absorber mirrors (SESAMs) has been investigated. SWCNT-SAM mode-locking has been optimized in Nd-doped bulk lasers for the first time, yielding 99-fs pulses at 1070 nm. For comparison, by using a SESAM instead of SWCNT-SAM, pulses as short as 87 fs and a tuning range of 30 nm were achieved. Related to the applied 200-mW single-mode laser diode as pump source the lasers were characterized by high efficiency and low threshold. The optimized low-power pump setup yielded a remarkable slope efficiency of 46.5% in the cw regime.
