What helps make LBO Specific is its blend of a large transparency selection, extending through the ultraviolet into the considerably infrared, and an exceptionally high injury threshold.
LBO nonlinear crystals have outstanding physical Attributes, like large thermal steadiness, higher harm threshold, and broad transparency variety. The thermal conductivity of LBO is fairly reduced when compared to other nonlinear crystals, which makes it extra liable to thermal outcomes.
But LBO has far better transparency, fewer flaws, and would not suffer from grey tracking. The result is greater power and life span capability. It's also cheaper than hydrothermal KTP, so it's got begun to exchange KTP in the greater demanding apps.
As we keep on to harness the strength of these amazing crystals, one can only anticipate the extraordinary breakthroughs they assure to herald our long term.
It's worth noting the characterization strategies talked about Within this chapter are not limited to LBO nonlinear crystals and will be applied to other nonlinear crystals as well.
Remember to pick out your shipping and delivery state to perspective one of the most precise inventory details, and to find out the correct Edmund Optics gross sales office on your purchase.
Crystals for NCPM at an elavated temperature might be premounted in an oven with precision controller. Crystals utilised at ~ twenty - fifty oC can also be premounted in a compatible water-cooled or TEC (ThermoElectric Cooler) cooled mount on request.
LBO is the 1st choice for producing doubler or tripler for lasers including Nd:YAG exactly where high ability density, high security, and while operation are expected.
Type II NCPM OPO pumped by a XeCl excimer laser at 308nm has realized sixteen.5% conversion efficiency, and reasonable tunable wavelength ranges is usually obtained with different pumping sources and temperature tuning.
One of the most typical programs of LBO nonlinear crystals is frequency doubling, the place the basic frequency of a laser beam is doubled to more info create a higher frequency output.
When stacked up in opposition to other nonlinear optical crystals, LBO Crystals unmistakably maintain their ground. Their wide transparency vary is a particular trait that surpasses most other crystals in the sector.
But, it’s not pretty much endurance; these crystals glow brightly while in the realm of frequency doubling, Among the most widespread nonlinear optical processes.
SHG measurement can be utilised to find out the crystal good quality and defects, for example domain construction and non-uniformity.
Crystals which can be non-critically stage-matched inside a crystal oven might exhibit problems in the event the crystal temperature is improved far too speedily or also frequently. In particular, anti-reflection coatings might be damaged as a consequence of different thermal enlargement coefficients in the involved elements.
