Hygroscopic crystal resources deteriorate when they're not often stored in sufficiently dry air (or a dry purge gas). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It might be handy to help keep this type of crystal at a fairly elevated temperature, that makes it simpler to retain it dry.
In addition it has a very important application in economical technology of ultrabright entangled photons by way of blue pumped spontaneous parametric down conversions (SPDC).
5 mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical phase matching LBO crystals are perfect for next or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
Commonly, the crystal substance should have a large optical transparency for all wavelengths concerned �?by way of example, for pump, signal and idler in an optical parametric amplifier.
A not-for-profit Firm, IEEE is the world's biggest technical Experienced Corporation committed to advancing technological innovation for the good thing about humanity.
GWU-Lasertechnik has over thirty several years of expertise in distributing laser crystals. Pick out GWU to gain from our large understanding As well as in-industry experience!
The selection from the most fitted crystal content for a given software is usually considerably from trivial; it should require the consideration of numerous facets. One example is, a significant nonlinearity for frequency conversion of ultrashort pulses won't help if the interaction length is strongly limited by here a sizable team velocity mismatch as well as minimal harm threshold boundaries the applicable optical intensities.
Operation of nonlinear crystals at temperatures down below place temperature (to realize period matching) is generally problematic, as it could produce condensation of drinking water over the crystal surfaces If your surrounding air is just not pretty dry.
In the situation of ultrashort pulses the substantial group velocity mismatch enforces the use of a shorter crystal, which demands higher optical intensities to get a offered conversion efficiency.
Too much optical intensities all through Procedure may possibly promptly hurt a crystal. Regrettably, nonlinear crystals often need to be operated not considerably from their optical hurt threshold to realize a sufficiently higher conversion effectiveness. This means a trade-off in between conversion effectiveness and crystal lifetime.
Non-linear Optical (NLO) crystals supply an enormously versatile Alternative for producing new wavelengths from existing, off-the-shelf laser resources. The optical wavelength spectrum is utilized by a significant and regularly increasing a number of applications, from manufacturing of clinical lasers, quantum networking & computing through to environmental sensing along with quite a few Many others.
GWU-Lasertechnik presents all normal nonlinear crystals like LBO, BBO and KTP with a wide assortment of specifications. Beside the effectively-established supplies, revolutionary crystals like CLBO or BiBO with exceptional properties for e. g. deep-UV generation or superior-electrical power ultrashort pulse lasers can be found. Irrespective of if person parts for R & D applications are demanded or Value-effective quantities in tiny, medium or significant batches with in-time shipping and delivery for the output line are essential: GWU’s focused assistance helps to locate the best Main factors to your software.
linear absorption, which may induce heating at substantial optical electrical power concentrations, so that the phase matching is disturbed, and thermal lensing may come about
flux-developed KTP and RTP with its significant nonlinearity, also in variants with higher grey monitoring resistance
