Continuous-wave and mode-locked Cr4+:Ca2GeO4 lasers that use a fiber laser
pump source were demonstrated. The continuous-wave Cr4+:Ca2GeO4 laser yield
ed a maximum output power of 415 mW at 1420 nm and a tuning range of 1335-1
492 nm. With a saturable-absorber mirror, 60-ps pulses and 110-mW maximum o
utput power were generated from a passively mode-locked Cr4+:Ca2GeO4 laser.
