This article dives deep into the benefits and exceptional Attributes of BBO crystal and its paramount great importance in productive frequency doubling and harmonics era at 266nm.
Howdy, thanks for getting in contact with Thorlabs. The wavelength ranges from the antireflective coatings on these β-BBO crystals align with the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually produced by reaching out to us at [email protected]
Frequent cleansing and appropriate storage can help extend the lifespan of BBO crystals, making certain their continued contribution to the sphere of optics and photonics.
Now Evaluate the most Electrical power density to that which can be specified since the LIDT for the optic. In the event the optic was examined at a wavelength in addition to your running wavelength, the hurt threshold has to be scaled appropriately [3].
Following extraction, the BBO crystals are then cut into the specified styles and sizes. This chopping course of action is executed with precision instruments to make certain that the crystals are Minimize properly and cleanly.
The team velocity would be the pace of the heart beat, or even more formally the envelope of the electric area. The group index similarly governs the velocity in the envelope relative on the velocity of sunshine inside a vacuum and it is dependent on the dispersion of the material.
There are 2 velocities that define the propagation of light in optical media: the section and team velocities. The section velocity is the velocity on the copyright, the oscillation of the electrical subject, as well as the velocity that's matched in between the basic and 2nd harmonic frequencies for section matching. The phase velocity relative on the pace of light in the vacuum is described because of the index of refraction.
When one of those β-BBO Crystals is mounted from the RSP1 mount, the crystal will probably be centered about the eight-32 (M4) hole inside the mount's foundation without the need to have for spacers.
For consumer comfort the crystals can be mounted within an one" anodized aluminum (Al) mount. The mounted crystals could be further mounted in a traditional 1" mirror mount being angle tuned for period matching (as proven to the right). Drinking water-cooled mounts for prime power programs could be available on ask for.
For CPM, we Minimize our items at an angle equal to no or 90 concentrations stressing on the list of big axes. For NCPM, we minimized our things at an angle based on Snell’s regulation:
When comparing an LIDT specified for any pulsed laser towards your laser, it is important to find out the following:
They even have a substantial injury threshold, allowing for them to handle higher-power laser beams without the need of degradation. These distinctive Houses make BBO crystals a versatile Instrument in a variety of optical programs.
GWU-Lasertechnik has more than thirty years of encounter in distributing laser crystals. Decide on GWU to take pleasure in our huge expertise As well as in-subject working experience!
This is especially essential in industries like semiconductors and micro-electromechanical programs (MEMS), the place even a small mistake can render a ingredient ineffective or bring on sizeable losses. With BBO’s 266nm generation, industries can accomplish higher precision and reliability inside their read more fabrication procedures, driving innovation and products quality to new heights.
