Abstract

OPO technique has the advantage of producing pulsed mid-infrared radiation with broad wavelength coverage which makes up for the absence laser emission in certain band of frequencies. The 2.6 micrometer band lasers have many potential applications in fields such as industrial pollution sources monitoring [1,2].Moreover, KTA crystal features large non-linear optical and electro-optical coefficients and low crystal loss in the wavelength range 2.6-3.2 μm; high nonlinear coefficient; high optical damage threshold; low temperature sensitivity. KTA is also non-hygroscopic, and offers the possibility of critical phase matching with a high value of dλ/dθ which results in a narrow free running linewidth [3,4]. It has found wide applications in optical parametric oscillation/ amplification (OPO/OPA), and electro-optical Qswitching involving MIR wavelengths [5]. In this paper, we report on an intra-cavity pumped self-cascaded OPO-based on the NCPM KTA-OPO design [6,7] for the generation of a 2.59 μm high laser peak power.
