You have to think about the wavelength and electric power of your laser resource and select a crystal that may be transparent within the provided wavelength and may face up to the laser electric power. And lastly, other factors like the thermal steadiness, optical homogeneity, and nonlinear optical coefficient of the crystal also have to be viewed as.
LBO Crystals preserve their security under various ailments, demonstrating their versatility and resilience. However, their exceptional performance is usually accomplished beneath sure temperature and strain parameters.
Commonly, the crystal substance ought to have a higher optical transparency for all wavelengths concerned �?by way of example, for pump, sign and idler within an optical parametric amplifier.
It is actually value noting that the characterization approaches talked over In this particular chapter are certainly not limited to LBO nonlinear crystals and might be applied to other nonlinear crystals likewise.
The ideal crystal orientation for maximum SHG efficiency in LBO nonlinear crystals is the sort I period-matching route, which corresponds to your ninety-degree angle among the enter and output polarizations.
SHG and THG for Center and substantial electrical power Nd: lasers at 1064 nm for healthcare, industrial and navy apps
GWU-Lasertechnik delivers all conventional nonlinear crystals like LBO, BBO and KTP with a wide selection of technical specs. Beside the perfectly-established products, modern crystals like CLBO or BiBO with excellent Houses for e. g. deep-UV generation or large-power ultrashort pulse lasers are offered. Despite if specific pieces for R & D uses are demanded or Charge-successful numbers in small, medium or massive batches with in-time shipping with the production line are essential: GWU’s dedicated support really helps to find the ideal Main elements for the software.
In the situation of ultrashort pulses the significant team velocity mismatch enforces the usage of a shorter crystal, which calls for significant optical intensities to get a given conversion performance.
Optical parametric amplification (OPA) is actually a nonlinear process that consists of the conversion of a significant-Vitality photon into two lessen-Vitality photons. LBO nonlinear crystals Have got a significant nonlinear coefficient, that makes them ideal for efficient OPA.
If you don't find the appropriate merchandise higher than, you might let us know your needs or applications in the form beneath. Our sales or specialized workers can get back again to you personally at the earliest opportunity.
Numerous Houses of a nonlinear crystal could be vital for an application e.g. in nonlinear frequency conversion:
g. in the shape of “grey monitoring�? This sort of phenomena are significantly here frequent for Procedure with ultraviolet light-weight. Notice that a gradual degradation may guide into fast catastrophic destruction by means of abnormal heat generation.
Crystal progress is often a significant phase while in the creation of higher-quality LBO nonlinear crystals. The choice of crystal advancement technique can substantially impact the crystal quality and optical properties in the resulting crystal. The Czochralski, flux, and TSSG solutions are definitely the mostly made use of procedures to the production of LBO nonlinear crystals, Each individual with its positives and negatives.
