Optical parametric oscillation (OPO): We use OPO to determine our items�?nonlinear conversion overall performance and stage-matching angle for any specified enter wavelength and signal/idler wavelengths. We make certain that our products meet up with the requirements for OPO programs.

When the Rayleigh assortment is fewer than the crystal thickness, the space about which the beam is optimally powerful is less than the crystal thickness.
In an effort to use the desired CW damage threshold of an optic, it is necessary to learn the next:
The sort-I stage matching course of action depends on matching the normal and extraordinary indices of refraction for the basic and next-harmonic frequencies, which is attained by way of specific orientation from the crystal optic axis and enter propagation vector. A centered laser pulse, or beam, has angular content material, formally named spatial frequencies, to provide the compact focal location.

This publish-up will describe how we produce large-good quality BBO crystals at our company. We may also evaluation some benefits and complications of using BBO crystals for regularity conversion.
A second problem is that the team velocity mismatch between the next harmonic and elementary-frequency pulses will result in 1 pulse lagging here the opposite as the two propagate. This is called temporal walk-off and may occur even below best period-matched problems.
A5: Certainly, BBO crystals have exceptional thermal steadiness and can maintain their Houses at space temperature. Therefore they can be Utilized in a wide range of environments devoid of demanding Distinctive temperature Command.
A3: Of course, BBO crystals have a broad transparency assortment that extends in the ultraviolet spectrum. This will make them ideal for programs that have to have ultraviolet light-weight, which include UV spectroscopy and UV laser devices.
Hi, I was wanting to know if it's probable for you to provide a BBO crystal using a custom coating at 532nm fundamental and 266nm next harmonic technology. Greatest, Ben
The placement in the inexperienced curve relies on θ. In cases like this, the angle θ has been tuned to offer a refractive index for 515 nm light that matches the refractive index for 1030 nm gentle. This tuning angle is therefore optimized for Form-I SHG stage matching and a basic-frequency input beam of 1030 nm.
Third harmonic generation (THG): We use THG to evaluate our items�?nonlinear conversion efficiency and period-matching angle to get a given input wavelength. We Be sure that our items satisfy the specs for THG purposes.
This tends to make them extremely resilient and resilient, even further boosting their suitability for complicated optical purposes.
