The applications talked over in this chapter will not be restricted to LBO nonlinear crystals and will be placed on other nonlinear crystals as well. The development and optimization of various nonlinear optical products and purposes trust in the knowledge and application of those approaches.
You'll want to think about the wavelength and electric power within your laser resource and opt for a crystal that is definitely transparent at the specified wavelength and may endure the laser electricity. And finally, other elements such as the thermal security, optical homogeneity, and nonlinear optical coefficient with the crystal also need to be considered.
Lithium triborate (LBO) nonlinear crystal is one of the most utilised crystal for harmonics technology for brief and extensive pulse purposes. On account of it’s fairly compact walkoff angle extensive crystals might be utilized what will allow to attain superior conversion effectiveness. A special circumstance of LBO crystal application can be a non-essential phase matching (NCPM) for harmonics generation.
Past but not the very least, higher optical homogeneity assures uniform light-weight propagation from the crystal, resulting in much better beam excellent and much less distortions.
It really is worth noting which the characterization solutions discussed Within this chapter are certainly not restricted to LBO nonlinear crystals and can be placed on other nonlinear crystals as well.
The choice in the best suited crystal product for a supplied application is commonly much from trivial; it must require the consideration of many features. For example, a superior nonlinearity for frequency conversion of ultrashort pulses won't assist if the interaction duration is strongly restricted by a substantial team velocity mismatch plus the reduced damage threshold limits the applicable optical intensities.
LBO crystal (Lithium triborate) is actually a non-linear optical materials of option for frequency changing superior electricity lasers with its subsequent most important features:
The Czochralski technique allows for the manufacture of significant solitary crystals with great high quality, whilst the flux approach can minimize impurities and defects from the crystal. The TSSG strategy gives precise Manage about crystal orientation and defect density, as well as hybrid process combines the benefits of the TSSG and Czochralski approaches.
Variety II NCPM OPO pumped by a XeCl excimer laser at 308nm has attained 16.5% conversion efficiency, and average tunable wavelength ranges could be attained with distinct pumping sources and temperature tuning.
Non-linear Optical (NLO) crystals provide an enormously versatile Answer for creating new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is used by a big and regularly expanding selection of apps, from production of healthcare lasers, quantum networking & computing via to environmental sensing as well as several others.
Along with that, the large hurt threshold �?the ability of LBO Crystals to face up to higher-depth laser beams without the need of compromising their framework or functionality �?can be a A great deal-appreciated high quality, specifically in high-ability laser more info apps.
They can have top-quality beam excellent to your lasers which they substitute for, while accomplishing in hostile environments with at least upkeep.
The selection of strategy relies on the precise Houses that must be characterized, for example crystal framework, defects, and optical Homes.
LBO nonlinear crystals have one of a kind properties which make them ideal for numerous purposes in optics and photonics. This chapter discusses several of the most common purposes of LBO nonlinear crystals.
