Abstract :
Summary form only given. In the present paper, we discuss scaling to high output powers without using higher pump powers. This is particularly important for the gain media in the fluoride material system that exhibit low thermal conductivity, and even more so for gain media that exhibit nonradiative processes that decrease power rapidly as temperature rises, such as Cr:LiSrAlF/sub 6/. The recent arrival of diffraction-limited high-power laser diodes has made possible increases in pumping efficiency. We evaluate the suitability of the red diffraction-limited laser diode for use in a saturable Bragg reflector (SBR) mode-locked Cr:LiSrAlF/sub 6/ laser.
