Continuous-wave and passively mode-locked operation of a cunyite (Cr~(4+):Ca_(2)GeO_(4)) laser

摘要

Continuous-wave and mode-locked Cr~(4+):Ca_(2)GeO_(4) lasers that use a fiber laser pump source were demonstrated. The continuous-wave Cr~(4+):Ca_(2)GeO_(4) laser yielded a maximum output power of 415 mW at 1420 nm and a tuning range of 1335-1492 nm. With a saturable-absorber mirror, 60-ps pulses and 110-mW maximum output power were generated from a passively mode-locked Cr~(4+):Ca_(2)GeO_(4) laser.
