Efficient high-power (900-mW) TEM{sub 00} cw operation of a Cr:LiSrGaF laser pumped by a Kr{sup +} laser is demonstrated. The results of laser and spectroscopic analysis, including upconversion and excited-state absorption, are presented and used for the optimization of this laser. Kr{sup +}-laser-pumped mode-locked femtosecond operation (64 fs) was performed. Use of a modified resonator, which can decrease the threshold pump and intracavity power for Kerr-lens mode locking and increase the mode-locked output power (300 mW), is suggested. The influence of crystal axis misalignment on the tuning and mode-locking characteristics of the laser is studied. {copyright} {ital 1996 Optical Society of America.}
