【摘要】：報道了一種基于光纖可飽和吸收體的納秒脈沖摻銩全光纖雙腔激光器。該激光器采用線型雙腔結構,采用1550nm連續(xù)光纖激光器作為抽運源,以光纖布拉格光柵作為波長選擇器件,利用摻銩光纖的可飽和吸收特性,同時結合雙諧振腔間的相互作用,獲得穩(wěn)定的納秒脈沖輸出。分別采用單包層銩鈥共摻光纖和雙包層摻銩光纖作為增益介質,研究二者對激光輸出性能的影響,并進行優(yōu)化對比,最終實現平均功率為256.3mW,最窄脈寬為87ns的1993nm激光輸出,脈沖重復頻率在20.0~33.3kHz范圍內可調。
[Abstract]:A nanosecond pulse thulium doped all-fiber dual-cavity laser based on fiber saturable absorber is reported. The laser adopts linear double cavity structure, 1550nm CW fiber laser as pump source, fiber Bragg grating as wavelength selective device, and the saturable absorption characteristics of thulium doped fiber as well as the interaction between double resonators. Stable nanosecond pulse output is obtained. Single cladding thulium holmium doped fiber and double cladding thulium doped fiber were used as gain media respectively. The effects of the two on the laser output performance were studied and optimized. The 1993nm laser output with an average power of 256.3 MW and the narrowest pulse width of 87ns was achieved. The pulse repetition rate is adjustable in the range of 20.0 ~ 33.3kHz.
