If you don't find the acceptable solutions above, you could possibly let us know your specifications or applications in the form beneath. Our product sales or complex staff will get again for you immediately.
Additionally, it has a vital application in effective era of ultrabright entangled photons via blue pumped spontaneous parametric down conversions (SPDC).

Crystal life time can even be strongly dependent on the material quality, Despite the fact that specific degradation phenomena look like intrinsic restrictions of the material.
Also, it may be remarkably attractive to use a crystal content which can be critically phase-matched at area temperature simply because noncritical stage matching often includes the Procedure on the crystal inside a temperature-stabilized crystal oven. Having said that, the feasibility of important stage matching can be provided just for adequately high peak powers.
Applying our promoting bundle, you are able to Display screen your symbol, further more down below your product description, and these will been seen by several photonics gurus.
Observe that whether or not the nominal depth is beneath the nominal problems threshold, there may be challenges on account of fluctuations while in the beam power or neighborhood intensity (e.g., if a beam profile has “scorching spots�?, or resulting from isolated defects in a very crystal, that happen to be additional delicate as opposed to typical crystal substance.
Bismuth Triborate (BiB3O6 or BIBO) is actually a recently produced nonlinear here optical crystal. It possesses big powerful nonlinear coefficient, substantial damage threshold and inertness with regard to moisture.
In the case of ultrashort pulses the high team velocity mismatch enforces using a shorter crystal, which needs substantial optical intensities for your offered conversion efficiency.
Borates which include LBO and BBO also function properly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
In many situations, a nonlinear crystal useful for nonlinear frequency conversion has an exceedingly long life time, that's longer than that of the whole laser procedure. The crystal product is actually not modified for the duration of Procedure. Nonetheless, a lessened crystal lifetime can arise beneath several 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。
The magnitude of the efficient nonlinear coefficient is dependent upon the nonlinear tensor elements and over the used period-matching configuration. A superior nonlinearity is essential specifically If your achievable optical intensities are reduced.
g. in the shape of “grey monitoring�? Such phenomena are notably popular for Procedure with ultraviolet light-weight. Take note that a gradual degradation may also guide into prompt catastrophic injury by means of abnormal warmth technology.
