● Reasonable price and quantity discount

● Technical support

● AR-coating, re-polishing service.

APPLICATION:

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.

Its application includes:

● 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.

ADVANTAGE:

● Large nonlinear coefficient

● Wide angular bandwidth and small walk off angle

● Broad temperature and spectral bandwidth

● Large electro-optical coefficient

● High damage threshold

● Nonhygroscopic, chemically and mechanically stable
