Applications
Due to the unique combination of its properties – high nonlinear coefficient, high damage threshold, non-hygroscopic, KTP can be used in both commercial and military lasers including medical and laboratory systems, range finders, designators and systems for use in semiconductor industry. SHG, SFG of Nd Lasers; Optical Parametric Generation (OPG, OPA, OPO); Electro-Optical modulations; Optical waveguide for integrated NLO and E-O devices; ØSHG, SFG of Nd lasers; Below figure shows the non-critical phase-matched (NCPM) X-cut KTP OPO/OPA. For pumping wavelength range from 0.7μm to 1 μm, the output can cover from 1.04μm to 1.45μm(signal) and from 2.15μm to 3.2μm(idler). More than 45% conversion efficiency was obtained with narrow output bandwidth and good beam quality. ØElectro-Optical Modulation; KTP also has promising E-O and dielectric properties that are comparable to LiNbO3. These properties make KTP extremely useful in various E-O devices. Oven for Heating KTP crystals; Increasing the temperature of KTP crystal can enhance the damage threshold of KTP crystal. Therefore, for high power or high power density SHG of Nd lasers, heating KTP to a certain temperature (e.g. 80——100deg) is recommended. CRYSTECH provides precision oven with temperature controller for heating KTP. A full assembly including KTP crystal, oven and temperature controller is also available
