Abstract

KTA, with its broad transparency range extending up to 5.5 µm, has been demonstrated to be an attractive optical-parametric-oscillator (OPO) material¹ with a high damage threshold (>500 MW/cm²). The development of Nd:KTA is a result of the efforts to develop new nonlinear materials that can exhibit optical parametric interaction as well as lasing action. We have developed an Nd: MgO: LiNbO₃-based OPO/ laser (OPOL). This device uses diode pumps at 810 nm to produce lasing at 1085 nm, and this lasing acts as a pump to induce optical parametric interaction in a single crystalline medium.²
