LBO is a superb NLO crystal for OPOs and OPAs which has a commonly tunable wavelength assortment and high powers. The exceptional Attributes of sort I and type II stage matching plus the NCPM depart a giant place from the investigate and applications of LBO's OPO and OPA.
Even when the crystal content or coating isn't delicate to drinking water, small water droplets may perhaps focus laser radiation a lot more tightly than beneath regular Procedure, and so hurt the crystal product.
the chemical toughness; e.g., some crystal elements are hygroscopic, Other individuals endure chemical adjustments when heated inside of a vacuum chamber for software of the dielectric coating
The amount of the solvent is often altered for different crystal sizing And so the lens tissue is saved moist for the entire drag but there is not any noticeable trace of solvent around the crystal floor after the drag is concluded. Inspect the floor and repeat if required, but only use Every sheet of lens tissue after.
It truly is well worth noting which the characterization procedures talked about Within this chapter aren't restricted to LBO nonlinear crystals and will be applied to other nonlinear crystals in addition.
The optimum crystal orientation for max SHG efficiency in LBO nonlinear crystals is the kind I period-matching way, which corresponds to a ninety-degree angle in between the input and output polarizations.
LBO crystal (Lithium triborate) is usually a non-linear optical substance of choice for frequency converting high ability lasers with its pursuing primary features:
They allow these large electricity units to achieve their peak efficiency although guaranteeing toughness, owing to their large damage threshold.
Optical microscopy is actually a usually utilized technique for characterizing the surface morphology and defects in LBO nonlinear crystals. Optical microscopy includes illuminating the crystal with a beam of sunshine and observing the reflected or transmitted mild through a microscope. By examining the surface morphology and defects, the crystal high-quality is usually decided.
Diode pumped reliable state lasers with frequency converting LBO are extremely trusted, compact, and use significantly less Electrical power than the traditional lasers they usually switch. In many scenarios there was no suitable or reasonably priced laser to accomplish LBO Crystal the functions that DPSS lasers have enabled.
If you do not find the appropriate products and solutions over, chances are you'll allow us to know your demands or apps in the shape underneath. Our sales or technical workers will get back again to you without delay.
LBO features a minimal susceptibility to dampness. End users are recommended to supply dry conditions for both the use and preservation of LBO.
PL spectroscopy may be used to discover impurities and defects in LBO nonlinear crystals that could have an impact on their functionality in different applications. PL spectroscopy can even be employed to determine the crystal excellent and homogeneity.
The BO3 groups are arranged inside a triangular configuration, forming a six-membered ring inside the crystal structure. The Li ions occupy the interstitial web pages involving the BO3 groups.
