The TSSG method is a relatively new strategy which includes acquired attractiveness for its capability to make superior-high-quality crystals with minimal defect density.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are resources with a comparatively strong nonlinearity. They are sometimes used for nonlinear frequency conversion and in addition for electro-optic modulators. Equally resources can be found in congruent and in stoichiometric sort, with critical distinctions relating to periodic poling and photorefractive effects (see under). Lithium niobate and tantalate are the most frequently utilized products while in the context of periodic poling; the ensuing resources are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric variations.

Lithium triborate (LBO) nonlinear crystal is Probably the most employed crystal for harmonics technology for short and prolonged pulse applications. Resulting from it’s reasonably tiny walkoff angle long crystals may be utilised what allows to accomplish high conversion effectiveness. A Particular scenario of LBO crystal application is often a non-vital period matching (NCPM) for harmonics era.

Having the crystal Reduce for NCPM and trying to keep the crystal at specific temperature, the walkoff angle is almost zero, consequently it permits to possess a really extended crystal and attain excellent conversion performance. The LBO crystal is usually used to generate next and third harmonics of neudymium primarily based lasers like Nd:YAG, Nd:YVO4. A different significant software with the LBO crystal is frequency conversion in optical parametric oscillators (OPO).

A substantial injury threshold, as witnessed in LBO Crystals, allows the crystal to resist intensive gentle with out sustaining destruction, maximizing the longevity and reliability of the optical setup. Furthermore, the character of one's laser process is a vital variable.

Optical parametric oscillation (OPO) is a nonlinear method that involves the conversion of the substantial-Electrical power photon into two lessen-Strength photons within a resonant cavity. LBO nonlinear crystals Have a very higher nonlinear coefficient, that makes them perfect for productive OPO.

LBO can arrive at equally temperature NCPM and spectral NCPM (with an exceptionally large spectral bandwidth) at 1300 nm. This really is favorable for your SHG of really broadband or ultrafast pulses at ~ 1300 nm.   

These circumstances, however, aren’t established in stone and largely count on the supposed application in the crystal along with the intricacies with the laser process design. Usually, in terms of temperature,

Also, LBO Crystals boast a big nonlinear coefficient. This trait is significant in nonlinear optical processes which include frequency doubling, the place it facilitates effective conversion with the incident mild to a unique frequency.

Optical parametric amplification (OPA) can be a nonlinear procedure that consists of the conversion of the higher-Electricity photon into two reduce-Electricity photons. LBO nonlinear crystals have a superior nonlinear coefficient, which makes them ideal for economical OPA.

Significant depth, short pulse lasers with quick wavelengths have enabled lots of manufacturing processes, or improved the final results obtained from far more conventional lasers. All those traits make doable a much more compact, even negligible HAZ (heat affected zone) about the location of beam impingement.

The magnitude in the efficient nonlinear coefficient depends upon the nonlinear tensor factors and about the utilized period-matching configuration. A large nonlinearity is important particularly Should the achievable optical intensities are very low.

 )  to blow off dust and also other unfastened contaminants initially. If a dry nitrogen line is offered from the lab, an air gun may also be applied  to blow absent dust particles. Blow off the surface area gently. Will not blow off the crystal itself from the hand!

Crystal progress more info is a crucial move from the production of high-excellent LBO nonlinear crystals. The choice of crystal advancement approach can considerably effects the crystal excellent, defect density, and optical Qualities of your resulting crystal.
