Optical parametric oscillation (OPO): We employ OPO to determine our merchandise�?nonlinear conversion overall performance and stage-matching angle for just a supplied enter wavelength and sign/idler wavelengths. We make selected that our goods fulfill the necessities for OPO purposes.

BBO is the only real NLO product which may be used to provide the fifth harmonic generation (5HG) of Nd:YAG lasers at 213 nm. Thanks to a little acceptance angle and huge angular walkoff, excellent laser beam quality (tiny divergence, very good method problem, etcetera.

A1: Of course, BBO crystals Have a very large damage threshold, creating them ideal for higher-power laser programs. Their ability to resist superior laser intensities without the need of struggling from optical destruction can make them a superb option for frequency conversion in large-power lasers.

) is The main element for BBO to obtain significant conversion efficiency. Limited aim of laser beam is not really advised.

BBO is of specific relevance while in the noticeable and much UV. Lots of period-matching apps are possible, such as the following:

Even so, to totally make use of the possible of BBO crystals, it really is crucial to grasp their Attributes and how to take care of and store them thoroughly. These crystals demand thorough managing to circumvent harm to their surfaces and should be saved within a dry, amazing put to take care of their optical functionality.

Now Look check here at the maximum electrical power density to that which happens to be specified because the LIDT with the optic. In case the optic was analyzed in a wavelength other than your working wavelength, the problems threshold need to be scaled correctly.

We also gauge the improved pulses�?temporal pulse shape and spectral transmission ability. We make sure that our goods meet up with the requirements for OPCPA apps.

We also layer our merchandise with anti-reflection levels to lower illustration losses in the crystal surfaces.

To forestall this, BBO crystals must be stored inside a dry atmosphere and effectively sealed when not in use. Also, any cleaning procedure should be accompanied by extensive drying to remove any residual humidity.

The performance of the SHG approach decreases significantly as the elemental beam diverges from its concentration, since the pulse Vitality is distributed across a larger beam cross part.

The production of Beta-Barium Borate (BBO) crystals is a posh and meticulous method that requires a high standard of precision and knowledge. This method, generally known as the flux method, starts Using the preparing of a mixture of barium borate and barium fluoride.

Understanding Crystal is akin to appreciating the bedrock of advanced optical technology. At its essence, BBO, or Beta Barium Borate, stands for a nonlinear optical crystal. The phrase “nonlinear�?here signifies the one of a kind potential of the crystal to connect with light inside of a method that alters The sunshine’s frequency.

Optical parametric amplification (OPA): We use OPA to measure our pieces�?nonlinear conversion overall performance and phase-matching angle to get a delivered enter wavelength and signal/idler wavelengths. We assurance that our merchandise satisfy the specs for OPA programs.
