If you don't locate the ideal items over, you might allow us to know your specifications or apps in the shape underneath. Our revenue or technical team can get back again to you without delay.

Inertness to Humidity: BIBO crystal is inert to dampness, which means it doesn't degrade or get rid of its optical Qualities when subjected to humidity. This can make BIBO a far more steady and reputable option for optical purposes in several environments.

5 mm to attenuate group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are ideal for next or third harmonic era of Nd:YAG and Yb:doped lasers.

The level of the solvent might be adjusted for different crystal sizing Therefore the lens tissue is kept moist for the entire drag but there is not any visible trace of solvent around the crystal floor after the drag is completed. Inspect the area and repeat if required, but only use Each individual sheet of lens tissue as soon as.

Also, it could be very desirable to employ a crystal substance which can be critically section-matched at home temperature simply because noncritical section matching typically entails the Procedure of more info the crystal within a temperature-stabilized crystal oven. Even so, the feasibility of vital section matching could possibly be offered just for adequately large peak powers.

Dust and stains on crystal surfaces could cause scattering/loss of light and can even react with light to break optical surfaces in a substantial incident laser energy.

The choice on the most fitted crystal product to get a presented application is usually much from trivial; it really should contain the consideration of numerous aspects. For instance, a large nonlinearity for frequency conversion of ultrashort pulses does not assist When the interaction duration is strongly minimal by a considerable group velocity mismatch plus the lower injury threshold limits the relevant optical intensities.

Procedure of nonlinear crystals at temperatures down below area temperature (to obtain phase matching) is usually problematic, as it could lead to condensation of water about the crystal surfaces Should the surrounding air isn't quite dry.

rystal surface is horizontal and a bit earlier mentioned your fingers. Take a refreshing, thoroughly clean sheet of lens tissue and location it around the crystal.  Make certain the lens tissue can be drawn through the crystal area. Upcoming, area a small drop of pure isopropyl Alcoholic beverages (IPA) to the lens tissue on top of the crystal area.

Many various Homes of a nonlinear crystal might be critical for an application e.g. in nonlinear frequency conversion:

In many scenarios, a nonlinear crystal utilized for nonlinear frequency conversion has a very prolonged lifetime, that is lengthier than that of the whole laser system. The crystal substance is actually not modified during Procedure. Nonetheless, a diminished crystal life time can manifest below a variety of situations:

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

Optical crystals can show distinct kinds of optical nonlinearities, which may be used in a variety of methods:

flux-developed KTP and RTP with its superior nonlinearity, also in variants with superior grey monitoring resistance
