The highest-seeded Answer progress (TSSG) approach is a comparatively new procedure which includes gained reputation in recent times for the manufacture of large-high quality LBO nonlinear crystals.
This resistance to thermal effects is realized owing to their exceptional crystal structure, which remains stable and unchanged even underneath major thermal strain.
We provide 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 be pre-set up to the oven gratis within our factory for the ease.
The flux approach permits the manufacture of big LBO crystals with minimal defect density and substantial optical high-quality. The use of a flux may also help to lower impurities and defects from the crystal, resulting in enhanced crystal top quality.
five mm to reduce team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are perfect for next or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
The most common utilization of LBO is In brief pulse, large pulse charge lasers; the higher electrical power density the higher. It is additionally incredibly well matched for non-critical phase matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at 90% conversion effectiveness with no stroll-off.
Optical microscopy can be used to detect surface area defects, such as scratches, cracks, and pits, which can influence the efficiency of the crystal in many programs. Optical microscopy can also be applied to determine the crystal thickness and uniformity.
Further more enriching their optical charm is the broad acceptance angle. This aspect allows for additional substantial gentle conversation and minimizes the requirements for beam alignment, simplifying the overall operation.
In the case of ultrashort pulses the high group velocity mismatch enforces using a shorter crystal, which necessitates large optical intensities for just a specified more info conversion efficiency.
Borates including LBO and BBO also function nicely in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Significant intensity, brief pulse lasers with shorter wavelengths have enabled a lot of manufacturing procedures, or improved the results received from a lot more traditional lasers. All those qualities make possible a Substantially smaller sized, even negligible HAZ (warmth affected zone) all over the location of beam impingement.
LBO has a minimal susceptibility to humidity. Users are suggested to offer dry disorders for each the use and preservation of LBO.
SHG measurement can be applied to find out the crystal quality and defects, for instance domain framework and non-uniformity.
They exhibit great homogeneity above massive volumes and also have a substantial problems threshold, but are hygroscopic and possess a very low nonlinearity.
