Advances in divalent transition-metal lasers
Abstract
The pulse-pumped performance of Ni:MgF2 and Co:MgF2 lasers has been compared, and shows a limitation of about 40% to the quantum efficiency of the Ni:MgF2 laser. The efficiency of the Co:MgF2 laser is near unity, and this device has produced 7.3 W of average power output at 1.92 micron, at a 50-Hz repetition rate. The Co:MgF2 laser has been tuned from 1.6 to 2.3 microns and Q-switched to generate pulses with 80 kW of peak power. Evaluation of the characteristics of the CW V:MgF2 laser indicates the presence of considerable excited-state absorption.
