An optical parametric oscillator using KTP and LBO nonlinear crystals for the generation of continuously tunable coherent infrared radiation
Abstract
The need for high power coherent broadly tunable sources has been the motivating factor for the study of the Optical Parametric Oscillation (OPO) for many years. With the advent of new nonlinear crystals, better mirror coating techniques and improved pump lasers, the interest in OPO has been renewed. OPO devices have many advantages over other tunable sources; all solid state, large tuning ranges, good conversion efficiency, small size, no harmful chemicals, no need for cryogenic cooling and can be pumped by low power devices (diode lasers) . Using the new nonlinear crystal potassium titanyl phosphate (KTP) in an OPO device pumped by a Nd:Yag laser (1.064 μm), a wavelength tuning range of 1.8 μm to 2 .3 μm was obtained, with peak conversion efficiency of 14%. Using the new nonlinear crystal lithium triborate (LBO) in an OPO device pumped by a doubled Nd:Yag laser (532 run), a wavelength tuning range of 815 run to 1.3 μm was obtained, with a peak efficiency of 25% •
