The optimum angle will depend on the sort of nonlinear method, the wavelength, and the crystal thickness. Other approaches for acquiring phase-matching in LBO nonlinear crystals involve temperature tuning and quasi-section matching.
You must look at the wavelength and electricity of one's laser source and pick a crystal that's clear in the offered wavelength and may endure the laser electric power. Finally, other elements including the thermal steadiness, optical homogeneity, and nonlinear optical coefficient on the crystal also should be deemed.
Lithium triborate (LBO) nonlinear crystal is Probably the most applied crystal for harmonics generation for brief and lengthy pulse programs. As a consequence of it’s fairly compact walkoff angle extended crystals could be utilized what makes it possible for to attain significant conversion efficiency. A Specific circumstance of LBO crystal application is usually a non-essential section matching (NCPM) for harmonics technology.
The flux approach permits the manufacture of huge LBO crystals with reduced defect density and significant optical top quality. The use of a flux might help to lower impurities and defects within the crystal, resulting in enhanced crystal high-quality.
The wonderful optical homogeneity and deficiency of inclusions in GAMDAN product imply excellent undistorted wavefront output from the machine. LBO has an exceedingly substantial inside damage threshold as a result of its reduced absorption. That property also avoids beam distortion from thermal expansion.
The method is also fairly fast and might create crystals with substantial expansion charges. Even so, the TSSG technique necessitates mindful control of the cooling charge, seed crystal dimension, and focus of your commencing components to keep up uniform crystal development.
LBO can attain both equally temperature NCPM and spectral NCPM (with an incredibly wide spectral bandwidth) at 1300 nm. This can be favorable to the SHG of quite broadband or ultrafast pulses at ~ 1300 nm.
GWU-Lasertechnik delivers all standard nonlinear crystals like LBO, BBO and KTP which has a broad range of requirements. Beside the very well-recognized materials, ground breaking crystals like CLBO or BiBO with exceptional Houses for e. g. deep-UV era or superior-electric power ultrashort pulse lasers can be obtained. No matter if unique pieces for R & D functions are expected or Expense-successful numbers in modest, medium or huge batches with in-time supply for that generation line are needed: GWU’s focused service helps you to discover the best core factors for the application.
L-B-O, what exactly is it good for? Absolutely the most beneficial frequency doubling and tripling crystal once you are searching for by far the most robust and damage resistant product.
Diode pumped reliable point out lasers with frequency changing LBO are extremely responsible, compact, and use much less Strength than the standard lasers they frequently swap. In many conditions there was no suited or affordable laser to click here complete the features that DPSS lasers have enabled.
Inspect the crystal area for dust and stains by Keeping it in close proximity to a bright obvious-light-weight resource. Viewing at distinctive angles may also help see scattering from dust and stains. The crystal surface area must be cleaned as described below if dust and stains are found.
Among the most typical apps is frequency doubling, where by LBO Crystals proficiently transform the frequency of the large ability laser, successfully halving the wavelength and opening up a spectrum of opportunities for laser apps.
Also, LBO Crystals have made substantial contributions towards the realm of optical parametric oscillation, a method essential for generating tunable mild sources. In this article, they serve as a platform for the incident light-weight to generate two new light-weight beams, Just about every carrying unique frequencies.
By examining the emitted light-weight, the luminescent Qualities and defects with the crystal may be decided.
