Abstract

We demonstrate a novel ring cavity for diode-pumped double-clad Tm-doped ber laser, which is constructed by placing the 45o angle-polished output end before the input end and the pump and laser power can re-launched into the ber. This design can reduce the reabsorption by using short length of bers without loss of pump efficiency. Furthermore, by adjusting the distance between the ber end and the objective lens, uni-directional output can be obtained. With a 80 cm long ber, 2.7 W single-mode continuous-wave output is generated for 11.5 W launched pump power.
