This effectiveness is significant, especially when one considers the era of the 266nm wavelength, where even slight inefficiencies can cause considerable Power losses.

Following, the power/Electricity is possibly improved or lowered and also the optic is exposed at ten new destinations. This method is recurring right until hurt is noticed. The harm threshold is then assigned being the best electricity/Strength that the optic can face up to without the need of leading to damage. A histogram including that down below represents the screening of 1 BB1-E02 mirror.

Once the Rayleigh vary is less than the crystal thickness, the distance more than which the beam is optimally rigorous is a lot less than the crystal thickness.

Now compare the most Electrical power density to that which happens to be specified because the LIDT for your optic. If your optic was tested at a wavelength in addition to your working wavelength, the destruction threshold needs to be scaled correctly [three].

BBO includes a minimal susceptibility to humidity. The AR coating or perhaps the protecting coating (P-coating) around the crystal faces can shield the faces from dampness to some extent. It is ok to go away the crystal from the  setup for many optics labs with RH =< forty%.  However, we suggest to retailer the crystal inside a desiccator if it will not be utilised for more than > 2 months to prolong the crystal life time.

). This spatial concentrating constraint about the SHG course of action will typically bring about the crystal duration normally staying a lot less than the Rayleigh variety of the enter concentrated pulse.

Temperature degree sensitivity: BBO crystals temperature sensitivity influences their refractive indices in addition to stage-matching issues. This needs temperature degree stabilizing or tuning instruments to keep optimum effectiveness.

We also gauge the enhanced pulses�?temporal pulse condition and spectral transmission ability. We Guantee that our products fulfill the requirements for OPCPA purposes.

The lifespan of BBO crystals will vary significantly based on quite a few elements. These contain how the crystals are utilized, how These are taken care of, as well as circumstances wherein They may be saved.

If you do not find the suitable solutions previously mentioned, it's possible you'll let us know your requirements or purposes in the shape under. Our sales or technical personnel will get again for you without delay.

Superior nonlinear coefficients: BBO crystals have sizeable nonlinear coefficients which make successful frequency conversion processes with low input electrical power requires doable.

BBO nonlinear crystal is really a negative uniaxial crystal. It offers period matching for many second-get interactions Practically about its full transparency assortment. This transparency ranges from 185 nm to three.three µm, as inferred from transmittance measurements employing crystal samples here of a few mm thickness.

Any contamination can degrade the optical performance on the crystal and likely cause injury underneath significant laser energy. When storing BBO crystals, they need to be put in the protective circumstance to prevent Bodily hurt and dirt accumulation.

Irrespective of whether you’re a researcher, a laser program designer, or an fanatic, we hope this informative article has answered your questions on BBO crystals.
