Nevertheless, This may be mitigated through the use of proper cooling procedures in the course of crystal progress and unit operation.

We offer precision oven and temperature controller to maintain LBO crystals at a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals can be pre-put in in to the oven free of charge inside our manufacturing facility for the advantage.

XRD may also be used to determine the crystal high quality and defects within the crystal, including twinning and dislocations.

Just about the most vital Homes of LBO nonlinear crystals is their capability to reach period-matching for economical frequency conversion. Period-matching would be the problem where by the wave vectors of the fundamental and harmonic waves match, enabling the conversion of the fundamental frequency to the harmonic frequency.

A seed crystal, normally a little LBO crystal, is gradually dipped into your soften and pulled up at a managed fee although becoming rotated to take care of uniform progress. As the seed crystal is pulled up, it consistently melts and solidifies to kind one crystal.

A hybrid approach that combines some great benefits of the Czochralski and TSSG approaches has also been developed to the creation of LBO nonlinear crystals. In this method, a small seed crystal is initially developed utilizing the TSSG technique, and then the crystal is connected into a rod and utilised as being a seed for that Czochralski approach. The ensuing crystal can be a hybrid crystal using a low defect density and significant optical high-quality.

LBO is the main option for earning doubler or tripler for lasers for example Nd:YAG where large here electrical power density, substantial security, and long time Procedure are needed. 

If the crystal surfaces remain “soiled�?just after the above mentioned cleansing procedures, the surfaces might have been broken. You should Get hold of us for rework of your crystals.

Among the most frequent apps of LBO nonlinear crystals is frequency doubling, exactly where the elemental frequency of the laser beam is doubled to produce an increased frequency output.

LBO is phase matchable for that SHG and THG of Nd:YAG and Nd:YLF lasers, utilizing both kind I or form II interaction. For that SHG at space temperature, form I phase matching is often reached and has the utmost helpful SHG coefficient inside the principal XY and XZ planes in a wide wavelength vary from 551 nm to about 3000 nm.

The Czochralski strategy permits the creation of large LBO crystals with outstanding crystal quality and very low defect density. However, the method is relatively slow and calls for thorough Charge of the temperature, rotation, and pulling charge to maintain uniform advancement.

LBO is actually a non-linear crystal.  The significance of which is it may alter the wavelength of the enter beam to a unique wavelength output.  GAMDAN LBO has primarily no absorption above an array of wavelengths, from 160 to 2600 nanometers.  Which means it is a superb choice for frequency tripling the emission of popular a person-micron lasers in the UV, at close to 355 nanometers.

Crystal progress is a vital action while in the manufacture of substantial-excellent LBO nonlinear crystals. The selection of crystal advancement method can substantially effect the crystal top quality, defect density, and optical Qualities on the ensuing crystal.
