New Step by Step Map For LBO Crystal

LBO is an excellent NLO crystal for OPOs and OPAs having a broadly tunable wavelength variety and high powers. The one of a kind Houses of sort I and type II stage matching as well as the NCPM leave a giant room during the exploration and applications of LBO's OPO and OPA.
On the other hand, This may be mitigated by utilizing right cooling techniques during crystal development and system operation.
But LBO has improved transparency, less flaws, and doesn't have problems with gray monitoring. The result is better power and life span capacity. It is usually more affordable than hydrothermal KTP, so it has started to replace KTP in the greater demanding apps.
Ordinarily, the crystal product ought to have a higher optical transparency for all wavelengths involved �?for example, for pump, sign and idler in an optical parametric amplifier.

The most typical utilization of LBO is In a nutshell pulse, superior pulse price lasers; the upper electric power density the better. It's also quite well matched for non-critical phase matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at 90% conversion performance without walk-off.
LBO can get to both of those temperature NCPM and spectral NCPM (with a very wide spectral bandwidth) at 1300 nm. This can be favorable for your SHG of quite broadband or ultrafast pulses at ~ 1300 nm.
Extreme optical intensities during operation may perhaps instantaneously problems a crystal. Sad to say, nonlinear crystals often have to be operated not much from their optical problems get more info threshold to achieve a sufficiently higher conversion performance. This means a trade-off amongst conversion performance and crystal life span.
Kind II NCPM OPO pumped by a XeCl excimer laser at 308nm has reached sixteen.5% conversion performance, and average tunable wavelength ranges may be acquired with distinct pumping resources and temperature tuning.
Overall, the characterization solutions reviewed In this particular chapter deliver precious insights in to the methods useful for the characterization of LBO nonlinear crystals.
XRD can be used to detect the crystal framework and orientation of LBO nonlinear crystals, which can be important for obtaining exceptional section-matching problems in various apps.
Probably the most widespread apps is frequency doubling, where by LBO Crystals efficiently convert the frequency of a superior electricity laser, successfully halving the wavelength and opening up a spectrum of opportunities for laser apps.
This wide range empowers them to connect with various laser resources, opening up a broad spectrum of programs throughout different scientific and industrial sectors.
The TSSG strategy allows for the manufacture of substantial-quality LBO crystals with lower defect density and excellent optical Homes. Using a seed crystal will help to manage the crystal orientation and defect density, bringing about improved crystal top quality.
