Excimer pumped deuterated L-arginine phosphate optical parametric oscillator

Abstract
The first optical parametric oscillator (OPO) using deuterated L-arginine phosphate is reported herein. The OPO pumped at 308 nm by an XeCl excimer laser generates broadly tunable output over the spectral ranges 415 to 526 nm and 1194 to 743 nm, using a critically phase-matched type I geometry. A study of the oscillation threshold has been made under conditions of different beam sizes and across the tuning range. A discussion of the damage problem in the material and the implications of 351 nm pumping are also given.
