High-precision laser microfabrication is a way wherever elements are processed and modified with a microscopic scale. This method requires a laser supply which will make particularly centered and precise beams of light. The 266nm wavelength is very ideal for this as a result of its shorter wavelength, which makes certain that the laser beam is usually centered to an incredibly tiny location size.
Beta Barium Borate (BBO) crystals have been a subject of curiosity in the sector of optics and photonics because of their special Qualities. In the following paragraphs, we goal to reply 10 common questions on BBO crystals, providing a comprehensive understanding of this interesting product.
Any scratches can degrade the optical functionality on the crystal and likely induce destruction beneath high laser electrical power. For stubborn stains, a solution of gentle detergent or isopropyl alcohol can be gently applied to the crystal surface area after which rinsed off with distilled water.
When a person of those β-BBO Crystals is mounted while in the RSP1 mount, the crystal is going to be centered around the 8-32 (M4) gap while in the mount's base with no want for spacers.
The period-matching abilities of BBO crystals deserve Unique mention. While in the intricate dance of photons, the place conversion from one particular wavelength to another is commonly sought after, the section-matching offered by BBO ensures that Vitality losses are negligible.
Remember to Take note that We now have a buffer designed in between the specified damage thresholds online and the tests which We've done, which accommodates variation between batches. Upon ask for, we can offer particular person examination data along with a screening certification.
When the above mentioned treatment gives an excellent guideline for LIDT values, be sure to Get in touch with Tech Support In case your wavelength is different from the required LIDT wavelength. When your energy density is under the modified LIDT on the optic, then the optic need to perform on your software.
These Attributes make BBO crystals very appealing in many apps, from laser frequency conversion to electro-optic modulation. Their wide transparency selection allows them to work which has a broad number of laser wavelengths, although their significant damage threshold assures they can cope with higher-ability laser beams with no degradation.
Now Examine the maximum Electrical power density to that and that is specified because the LIDT for the optic. When the optic was examined at a wavelength aside from your working wavelength, the hurt threshold should be scaled correctly [three].
Hence, the second harmonic pulse spectrum, revealed on the proper, contains a spectral width about the same as The perfect case. Preferably, each frequency in the basic pulse spectrum can be concurrently phase matched.
As are going to be reviewed under, there is a concentrating numerical aperture (NA) limitation into the SHG period-matching method exactly analogous for the spectral section matching limitation reviewed inside the previous section (
When evaluating an LIDT specified for just a pulsed laser for your laser, a-BBO Crystal it is vital to be aware of the subsequent:
When an enter pulse's spectral vary is equivalent to or narrower compared to the reference pulse, the generated second harmonic pulse includes a length that is definitely shorter by an element of one/√two along with a spectral width that is definitely broader by an element of √two.
This is especially very important in industries like semiconductors and micro-electromechanical techniques (MEMS), wherever even a minor error can render a element ineffective or bring on significant losses. With BBO’s 266nm generation, industries can obtain larger precision and reliability inside their fabrication procedures, driving innovation and product top quality to new heights.
