PriceList for Bib3o6 - KTP Crystal – WISOPTIC Detail:
KTP (KTiOPO4 ) is one of the most commonly used nonlinear optical materials. For example, it’s regularly used for frequency doubling of Nd:YAG lasers and other Nd-doped lasers, particularly at low or medium-power density. KTP is also widely used as OPO, EOM, optical wave-guide material, and in directional couplers.
KTP exhibits a high optical quality, broad transparency range, wide acceptance angle, small walk-off angle, and type I and II non-critical phase-matching (NCPM) in a wide wavelength range. KTP also has relatively high effective SHG coefficient (about 3 times higher than that of KDP) and fairly high optical damage threshold (>500 MW/cm²).
Regular flux-grown KTP crystals suffer from blackening and efficiency breakdown (“grey-track”) when used during SHG process of 1064 nm at high average power levels and repetition rates above 1 kHz. For high average-power applications, WISOPTIC offer high grey track resistance (HGTR) KTP crystals grown by hydrothermal method. Such crystals have a lower initial IR absorption and are less affected by green light than regular KTP, thus avoid the problems of harmonic power instabilities, efficiency drops, crystal blackening, and beam distortion.
As one of the major KTP source suppliers in the whole international market, WISOPTIC has high capability of material selection, processing (polishing, coating), mass production, fast delivery and long guarantee period of quality KTP. It is also worth to mention that our price is quite reasonable.
