SHG measurement is often a generally made use of system for characterizing the nonlinear optical Houses of LBO nonlinear crystals. SHG measurement requires shining a laser beam of a particular wavelength onto the crystal and measuring the intensity of the second-harmonic wave generated because of the crystal.
You need to think about the wavelength and electricity of the laser supply and opt for a crystal that's transparent in the given wavelength and might withstand the laser ability. Lastly, other elements including the thermal steadiness, optical homogeneity, and nonlinear optical coefficient on the crystal also have to be regarded as.
Lithium triborate (LBO) nonlinear crystal is Probably the most utilised crystal for harmonics technology for brief and extensive pulse programs. As a consequence of it’s fairly tiny walkoff angle extended crystals may very well be applied what allows to obtain high conversion performance. A Specific circumstance of LBO crystal application is often a non-crucial period matching (NCPM) for harmonics era.
As we carry on to harness the power of these remarkable crystals, one can only foresee the remarkable progress they guarantee to herald our long run.

GWU-Lasertechnik delivers all typical nonlinear crystals like LBO, BBO and KTP using a wide number of requirements. Beside the properly-founded products, revolutionary crystals like CLBO or BiBO with superb properties for e. g. deep-UV era or large-power ultrashort pulse lasers can be obtained. It does not matter if particular person parts for R & D purposes are expected or Expense-economical numbers in small, medium or significant batches with in-time shipping for that manufacturing line are needed: GWU’s devoted assistance helps to find the greatest core components for the software.
In the case of ultrashort pulses the superior team velocity mismatch enforces the usage of a shorter crystal, which requires high optical intensities for the presented conversion effectiveness.
The most common purposes of LBO nonlinear crystals is frequency doubling, the place the fundamental frequency of a laser beam is doubled to supply a better frequency output.
When stacked up against other nonlinear optical crystals, LBO Crystals unmistakably hold their floor. Their wide transparency selection is a particular trait that surpasses most other crystals in the sphere.
From the context of stress, LBO Crystals are typically employed under ambient pressure situations in most optical purposes. They keep their structural integrity and optical Houses beneath these situations, guaranteeing reliable performance.
Characterization methods are essential for comprehension the properties and more info optimizing the effectiveness of LBO nonlinear crystals in various purposes.
They show superior homogeneity around big volumes and have a superior injury threshold, but are hygroscopic and possess a low nonlinearity.
