Optical parametric oscillation (OPO): We use OPO to determine our products�?nonlinear conversion effectiveness and stage-matching angle for a provided input wavelength and signal/idler wavelengths. We make certain that our products meet up with the necessities for OPO purposes.

BBO crystals are developed using the flux strategy, a procedure that entails melting raw materials at high temperatures. The molten content is then slowly and gradually cooled to form a crystal. This method involves precise control of temperature and cooling level to make sure the crystal’s quality and integrity.

We decreased our boule into smaller sized merchandise As outlined by shopper specifications employing a ruby blade, or twine saw device. Following that, polish these pieces applying ruby powder or slurry on Forged iron or copper plates.

Among the list of defining features of BBO crystals is their large hurt threshold. Which means that they're able to endure significant levels of laser power without having going through degradation or destruction.

Even nicely below the edge for fast harm, some crystal resources show a continual degradation throughout the used volume, e.

Their distinctive Attributes make them a favored option for several demanding and substantial-precision optical programs.

Temperature degree sensitivity: BBO crystals temperature sensitivity impacts their refractive indices as well as stage-matching troubles. This requirements temperature level stabilizing or tuning tools to maintain ideal efficiency.

This distinction triggers period mismatch amongst several mild polarization elements when propagating by way of a BBO crystal. Altering the angle among the beam and crystal axes can compensate for this phase mismatch.

  )  to blow off dust and various loose contaminants to start with. If a dry website nitrogen line is offered during the lab, an air gun will also be used  to blow absent dust particles. Blow off the floor Carefully. Don't blow off the crystal alone from a hand!

For CPM, we Minimize our parts at an angle equal to no or ninety levels stressing among the list of significant axes. For NCPM, we minimized our items at an angle determined by Snell’s regulation:

When evaluating an LIDT specified to get a pulsed laser on your laser, it is crucial to grasp the following:

Pulsed lasers with superior pulse repetition frequencies (PRF) could behave similarly to CW beams. Sad to say, this is very dependent on variables which include absorption and thermal diffusivity, so there is absolutely no trusted method for determining whenever a substantial PRF laser will problems an optic due to thermal results.

As are going to be talked about under, You will find there's concentrating numerical aperture (NA) limitation on the SHG phase-matching process particularly analogous on the spectral phase matching limitation talked over while in the earlier section (

Optical parametric amplification (OPA): We use OPA to measure our items�?nonlinear conversion effectiveness and period-matching angle for your offered input wavelength and signal/idler wavelengths. We ensure that our items satisfy the specs for OPA programs.
