5 Essential Elements For LBO Crystal
Blog Article
LBO is a superb NLO crystal for OPOs and OPAs using a commonly tunable wavelength variety and significant powers. The exceptional Homes of form I and kind II phase matching and also the NCPM go away an enormous home within the exploration and purposes of LBO's OPO and OPA.
This resistance to thermal effects is attained due to their one of a kind crystal framework, which continues to be secure and unchanged even below considerable thermal worry.
We provide precision oven and temperature controller to take care of LBO crystals in a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals may be pre-set up in the oven free of charge inside our factory for your personal convenience.
Typically, the crystal material ought to have a high optical transparency for all wavelengths concerned �?by way of example, for pump, signal and idler within an optical parametric amplifier.
Raman spectroscopy is a powerful method for characterizing the vibrational Houses of LBO nonlinear crystals. Raman spectroscopy requires shining a laser beam onto the crystal and measuring the scattered light-weight at distinct wavelengths.
The tactic is additionally relatively rapidly and may develop crystals with superior growth rates. Nevertheless, the TSSG method calls for careful Charge of the cooling amount, seed crystal dimension, and focus on the starting supplies to take care of uniform crystal advancement.
A hybrid approach that combines the advantages of the Czochralski and TSSG solutions has also been produced to the production of LBO nonlinear crystals. In this process, a little seed crystal is very first developed utilizing the TSSG approach, then the crystal is hooked up to a rod and utilised being a seed for that Czochralski approach. The ensuing crystal is actually a hybrid crystal which has a reduced defect density and higher optical excellent.
UV lasers excel website at marking. Materials that are in any other case transparent, which includes common glass, lenses, and prisms, numerous varieties of plastics and natural and inorganic components is often exactly marked with frequency tripled light-weight.
Sort II NCPM OPO pumped by a XeCl excimer laser at 308nm has achieved 16.five% conversion effectiveness, and average tunable wavelength ranges is often received with distinctive pumping sources and temperature tuning.
Borates like LBO and BBO also function well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
By analyzing the depth of the next-harmonic wave, the nonlinear optical coefficients in the crystal can be determined.
But, it’s not nearly endurance; these crystals glow brightly during the realm of frequency doubling, The most popular nonlinear optical processes.
) to blow off dust along with other loose contaminants 1st. If a dry nitrogen line is available during the lab, an air gun may also be utilised to blow absent dust particles. Blow off the surface gently. Usually do not blow off the crystal alone from the hand!
They're able to endure substantial warmth without any sizeable overall performance reduction, making certain that your optical program continues to be responsible and efficient even in demanding scenarios.
