The TSSG method is a comparatively new system which includes attained level of popularity for its power to make higher-excellent crystals with very low defect density.
You have to take into account the wavelength and electric power within your laser supply and select a crystal that's clear on the offered wavelength and might endure the laser electricity. And lastly, other elements including the thermal security, optical homogeneity, and nonlinear optical coefficient with the crystal also need to be regarded.
Lithium triborate (LBO) nonlinear crystal is The most utilized crystal for harmonics technology for short and lengthy pulse apps. As a result of it’s fairly compact walkoff angle lengthy crystals may very well be utilized what will allow to attain substantial conversion performance. A Unique scenario of LBO crystal application is often a non-critical phase matching (NCPM) for harmonics technology.
In summary, the stability and general performance of LBO Crystals are influenced by a myriad of variables. Having said that, their inherent flexibility and adaptability to a variety of circumstances set them apart, producing them a responsible option for a myriad of apps.
The two have a comparatively very low injury threshold, but tend not to need to be operated at superior intensities due to their high nonlinearity. They have got a bent for photorefractive effects, which can be harmful for frequency conversion, but are used for, e.g., holographic knowledge storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive harm�?is dependent strongly on the fabric composition; e.g. it can be minimized via MgO doping and by utilizing a stoichiometric composition.
The characterization of LBO nonlinear crystals is essential for knowing their Qualities and optimizing their functionality in several applications. This chapter discusses the different characterization techniques used for LBO nonlinear crystals.
All round, the crystal advancement procedures talked over Within this chapter present more info precious insights in the procedures useful for the manufacture of higher-excellent LBO nonlinear crystals.
LBO Crystals exhibit higher thermal steadiness and continue on to function efficiently more than a broad temperature array. This broad range permits flexible program design and style and ensures that the crystal overall performance is not really compromised, even underneath fluctuating temperature problems.
If the crystal surfaces are still “soiled�?soon after the above mentioned cleansing procedures, the surfaces might need been ruined. Make sure you Make contact with us for rework of your crystals.
Nonlinear Crystals of both β-barium borate (BBO) or lithium triborate (LBO) are useful for frequency conversion of laser resources. BBO crystals element thicknesses from 0.2mm to 0.5mm to minimize team velocity mismatch and are perfect for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are perfect for 2nd or third harmonic generation of Nd:YAG and Yb:doped lasers.
If you do not locate the suited products and solutions above, you may let us know your necessities or purposes in the shape under. Our income or specialized personnel will get again to you personally without delay.
LBO includes a very low susceptibility to humidity. Buyers are encouraged to provide dry situations for the two the use and preservation of LBO.
PL spectroscopy may be used to recognize impurities and defects in LBO nonlinear crystals that could influence their effectiveness in numerous apps. PL spectroscopy can also be applied to find out the crystal high quality and homogeneity.
The BO3 groups are organized inside a triangular configuration, forming a 6-membered ring within the crystal framework. The Li ions occupy the interstitial sites in between the BO3 groups.
