Properties of a pulsed LiIO3doubly resonant parametric oscillator

Spectral and other properties of a ruby laser pumped LiIO
3
pulsed doubly resonant parametric oscillator (DRO) are reported. This device is tunable from 1.12 to 1.83 μ with peak powers of 100 kW and 10-percent efficiency. The stability of the DRO is discussed. The output of the DRO was doubled into the 5600- 9150-Å range using a second LiIO

crystal. Peak second-harmonic powers were 10-15 kW.
