In some instances, the mismatch can be tiny. For example, every time a β-BBO crystal is utilized to frequency double 1550 nm mild and provide 775 nm light-weight, the team velocity mismatch is only some femtoseconds for every millimeter.

On the other hand, it’s essential to Notice that although BBO crystals can transmit UV gentle, they should be taken care of with care when Employed in UV purposes to circumvent potential harm to the crystal and ensure safety.

Both equally have a relatively very low damage threshold, but will not have to be operated at substantial intensities because of their high nonlinearity. They've a tendency for photorefractive outcomes, which might be detrimental for frequency conversion, but are used for, e.g., holographic data storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive destruction�?relies upon strongly on the material composition; e.g. it could be diminished via MgO doping and by making use of a stoichiometric composition.

Borates which include LBO and BBO also perform perfectly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.

Second harmonic generation (SHG): We make the most of SHG to measure our goods�?nonlinear conversion efficiency and section-matching angle for your given input wavelength. We assurance that our items fulfil the requirements for SHG purposes.

Beta-Barium Borate, also referred to as BBO crystals, are a singular style of nonlinear optical crystal that have attained considerable recognition in the sphere of optics and photonics. These crystals are renowned for his or her extensive transparency selection, which extends within the ultraviolet to the in the vicinity of-infrared spectrum.

Filters underneath or the shape at the bottom can be employed to assist product search or make further more inquiries.

g. 20 μm. The group velocity mismatch within the thicker substrate product may not make a difference, as being the nonlinear conversation requires position only in the thin crystal. The substrate only serves to mechanically stabilize The skinny nonlinear crystal.

In quasi-stage matching, the crystal product is “poled�?to get up and down domains to counteract the period-mismatch of the fabric, in which the poling time period is specific into the wavelengths of conversation.

GWU-Lasertechnik delivers all normal nonlinear crystals like LBO, BBO and KTP having a broad assortment of requirements. Beside the properly-set up elements, modern crystals like CLBO or BiBO with excellent Attributes for e. g. deep-UV era or higher-ability ultrashort pulse lasers can be found. It doesn't matter if person items for R & D applications are necessary or Price-effective numbers in compact, medium or substantial batches with in-time delivery to the generation line are needed: GWU’s devoted services helps you to locate the best core parts to your software.

Hi, I had been pondering if It really is possible to suit your needs to supply a BBO crystal with a custom coating at 532nm elementary and 266nm second harmonic generation. Finest, Ben

Pulsed lasers with higher pulse repetition frequencies (PRF) may perhaps behave similarly to CW beams. Regrettably, this is very more info depending on factors for example absorption and thermal diffusivity, so there's no responsible technique for analyzing when a significant PRF laser will injury an optic as a consequence of thermal effects.

BBO crystals even have a substantial problems threshold, indicating they will face up to substantial levels of laser energy with out suffering destruction. This is especially significant in programs involving superior-electric power lasers. In addition, BBO crystals Have got a substantial nonlinear coefficient, which enables economical frequency conversion, a vital functionality in many optical devices.

Any imperfections while in the chopping system could probably influence the optical Homes in the crystals.
