The ideal angle is determined by the kind of nonlinear process, the wavelength, as well as the crystal thickness. Other methods for attaining phase-matching in LBO nonlinear crystals incorporate temperature tuning and quasi-section matching.
You'll want to evaluate the wavelength and ability within your laser resource and select a crystal that's transparent within the specified wavelength and can face up to the laser energy. And lastly, other components including the thermal stability, optical homogeneity, and nonlinear optical coefficient on the crystal also need to be viewed as.
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 very well be pre-mounted to the oven cost-free inside our factory in your comfort.
Take note that although the nominal depth is down below the nominal problems threshold, there might be complications as a consequence of fluctuations during the beam electric power or local depth (e.g., if a beam profile has “incredibly hot spots�?, or as a consequence of isolated defects within a crystal, which happen to be much more delicate as opposed to regular crystal product.
linear absorption, which often can bring about heating at high optical electricity degrees, so which the section matching is disturbed, and thermal lensing might arise

A hybrid method that combines some great benefits of the Czochralski and TSSG solutions has also been made for that production of LBO nonlinear crystals. In this technique, a little seed crystal is initial developed utilizing the TSSG approach, and after that the crystal is hooked up to a rod and applied as a seed with the Czochralski system. The resulting crystal is often a hybrid crystal having a small defect density and substantial optical quality.
GWU-Lasertechnik presents all typical nonlinear crystals like LBO, BBO and KTP using a broad selection of specifications. Beside the well-founded elements, impressive crystals like CLBO or BiBO with remarkable Homes for e. g. deep-UV generation or superior-electric power ultrashort pulse lasers are offered. It doesn't matter if individual items for R & D uses are necessary or Expense-successful numbers in smaller, medium or huge batches with in-time supply for your manufacturing line are wanted: GWU’s dedicated support helps to discover the most effective core components on your software.
In the case of ultrashort pulses the higher group velocity mismatch enforces using a shorter crystal, which necessitates large optical intensities for your specified conversion performance.
Diode pumped reliable point out lasers with frequency changing LBO are hugely reputable, compact, and use fewer Electrical power than the normal lasers they normally replace. In several instances there was no ideal or very affordable laser to complete the functions that DPSS lasers have enabled.
However, if the application calls for, these crystals can also face up to sure elevated pressure situations. It is often recommended to refer to which has a crystal professional or confer with precise company tips to find out the ideal problems to your distinct LBO Crystal and application.
The Czochralski method permits the creation of substantial LBO crystals with great crystal good quality and lower defect density. Even so, the strategy is comparatively gradual and involves watchful control of the temperature, rotation, and pulling amount to take care of uniform growth.
SHG measurement may also be made use of to ascertain the crystal quality and defects, like domain construction and non-uniformity.
LBO nonlinear crystals have unique Houses here that make them perfect for a variety of applications in optics and photonics. This chapter discusses some of the most typical purposes of LBO nonlinear crystals.
