Simple high-efficiency TEM{sub 00} diode-laser-pumped {ital Q}-switched laser
- Code 924, NASA Goddard Space Flight Center, Greenbelt, Maryland 20771 (United States)
A simple, efficient diode-laser-pumped {ital Q}-switched Nd:YAG laser is described that produces 2.25-mJ, TEM{sub 00}, 4-ns pulses up to 90 Hz with only 20 mJ of pump power. The laser has a zigzag slab geometry, side pumped with only one high-power quasi-cw diode bar. This performance approaches that of longitudinal pumping, demonstrating TEM{sub 00} mode operation with long-pulse and {ital Q}-switched slope efficiencies of 28% and 19%, respectively. Second- and fourth-harmonic efficiencies of {gt}50% and {gt}20% from 1064 nm without the use of external focusing optics were also demonstrated.
