Abstract

A tandem optical parametric oscillator (OPO) is used to convert radiation from 1.064 μ m to the mid-infrared. Spectral bandwidth narrowing close to 80 times compared with a conventional cavity was achieved by using a bulk Bragg grating as an outcoupler in a near-degenerate periodically poled K Ti O P O 4 OPO. The narrowed 2008 nm radiation was subsequently used for pumping the Zn Ge P 2 OPO, which was tunable between 3.3 and 5.2 μ m . Pulse energies of 170 μ J and pump depletion close to 70% were obtained in the Zn Ge P 2 OPO. To our knowledge this is the first time the output from a near-degenerate type I PPKTP OPO has been used for Zn Ge P 2 OPO pumping.
