5 Simple Techniques For LBO Crystal
Blog Article
The TSSG process is a comparatively new procedure which has acquired acceptance for its capacity to deliver large-quality crystals with small defect density.
The understanding of these techniques is essential for the design and optimization of LBO nonlinear crystals for several apps in optics and photonics.
Important Text: Nonlinear Crystals , SHG crystal , SFG crystal , LBO Crystal Lithium Triborate (LiB3O5 or LBO) is a kind of nonlinear crystal that is usually Employed in the era of substantial-electricity laser radiation. It's a substantial injury threshold along with a wide transparency range between the ultraviolet to your in the vicinity of-infrared area, rendering it well suited for various laser programs.
Possessing the crystal Reduce for NCPM and preserving the crystal at specific temperature, the walkoff angle is almost zero, therefore it allows to have a really extensive crystal and attain outstanding conversion efficiency. The LBO crystal is mostly utilized to create second and third harmonics of neudymium dependent lasers like Nd:YAG, Nd:YVO4. A different important application in the LBO crystal is frequency conversion in optical parametric oscillators (OPO).
In regards to the optical Attributes of LBO Crystals, they in fact current an impressive portfolio. The huge transparency selection, stretching from the deep ultraviolet to significantly infrared spectrum, allows LBO Crystals to interact with an enormous variety of laser mild resources, amplifying their flexibility in numerous apps.

Crystals for NCPM at an elavated temperature is usually premounted within an oven with precision controller. Crystals made use of at ~ twenty - fifty oC can be premounted within a compatible h2o-cooled or TEC (ThermoElectric Cooler) cooled mount on ask for.

Variety II NCPM OPO pumped by a XeCl excimer laser at 308nm has attained 16.five% conversion efficiency, and reasonable tunable wavelength ranges could be obtained with distinctive pumping sources and temperature tuning.
Further than superior ability lasers, this thermal steadiness extends LBO Crystals�?applicability to the big range of environments with varying temperature conditions.
When stacked up from other nonlinear optical crystals, LBO Crystals unmistakably hold their floor. Their wide transparency assortment is a particular trait that surpasses most other crystals in the sphere.
But, it’s not nearly endurance; these crystals glow brightly while in the realm of frequency doubling, Just about the most widespread nonlinear optical processes.
Optical crystals can show different sorts of optical nonlinearities, that may be used in various techniques:
Crystals which can be non-critically stage-matched in the crystal oven may possibly exhibit troubles if the crystal temperature is transformed way too speedily or way too typically. Particularly, anti-reflection coatings could possibly be ruined as a result LBO Crystal of distinct thermal expansion coefficients of the associated resources.
