Even if the crystal product or coating will not be sensitive to drinking water, tiny water droplets may perhaps target laser radiation far more tightly than below ordinary Procedure, and therefore hurt the crystal content.
We offer precision oven and temperature controller to keep up LBO crystals at a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals could possibly be pre-set up into the oven free of charge in our manufacturing unit for your personal benefit.
Raman spectroscopy can be utilized to establish impurities and defects in LBO nonlinear crystals that can impact their general performance in numerous applications. Raman spectroscopy may also be utilized to determine the crystal top quality and stage purity.
Just about the most critical Homes of LBO nonlinear crystals is their power to accomplish phase-matching for productive frequency conversion. Section-matching may be the ailment in which the wave vectors of the basic and harmonic waves match, enabling the conversion of the basic frequency into your harmonic frequency.
A seed crystal, commonly a little LBO crystal, is gradually dipped in to the melt and pulled up at a controlled fee when remaining rotated to take care of uniform expansion. Since the seed crystal is pulled up, it repeatedly melts and solidifies to type a single crystal.
X-ray diffraction is a powerful method for identifying the crystal structure and orientation of LBO nonlinear crystals.
Abnormal optical intensities throughout Procedure may quickly damage a crystal. Regrettably, nonlinear crystals normally need to be operated not far from their optical harm threshold to accomplish a sufficiently large conversion performance. This suggests a trade-off concerning conversion performance and crystal life time.
Dust and stains on crystal surfaces can result in scattering/reduction of light and may even react with light-weight to break optical surfaces in a substantial incident laser ability.
Optical parametric amplification (OPA) is really a nonlinear course of action get more info that includes the conversion of the higher-Electricity photon into two reduce-Electricity photons. LBO nonlinear crystals have a large nonlinear coefficient, that makes them ideal for economical OPA.
If you do not find the suited items above, it's possible you'll allow us to know your requirements or apps in the form down below. Our product sales or technological employees will get again to you right away.
PL spectroscopy is a powerful strategy for characterizing the luminescent Attributes of LBO nonlinear crystals. PL spectroscopy will involve shining a laser beam on to the crystal and measuring the emitted mild at diverse wavelengths.
In addition, LBO Crystals have produced significant contributions into the realm of optical parametric oscillation, a process important for producing tunable mild sources. Right here, they serve as a System to the incident mild to produce two new mild beams, Each individual carrying diverse frequencies.
Crystal advancement is usually a critical move in the creation of substantial-top quality LBO nonlinear crystals. The selection of crystal progress method can noticeably affect the crystal high quality and optical Houses from the ensuing crystal. The Czochralski, flux, and TSSG strategies will be the most often employed techniques to the creation of LBO nonlinear crystals, Every with its positives and negatives.
