Substantial-precision laser microfabrication is a technique in which resources are processed and modified over a microscopic scale. This method demands a laser resource that can develop really centered and exact beams of sunshine. The 266nm wavelength is especially well suited for this due to its brief wavelength, which makes sure that the laser beam might be focused to a very modest location measurement.

Sad to say, it might be very difficult to match the LIDT specification of the optic towards your laser. You will discover multiple regimes during which a pulsed laser can injury an optic and this relies over the laser's pulse length. The highlighted columns in the table under outline the related pulse lengths for our specified LIDT values.

Hi, thank you for getting in touch with Thorlabs. The wavelength ranges with the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations might be created by reaching out to us at [email protected]

When one particular of these β-BBO Crystals is mounted during the RSP1 mount, the crystal will probably be centered over the eight-32 (M4) hole inside the mount's base with no have to have for spacers.

Any contamination can degrade the optical efficiency of the crystal and likely induce problems below substantial laser energy. When storing BBO crystals, they need to be put in a very protective case to stop Actual physical problems and dirt accumulation.

As the second harmonic gentle propagates, its Strength flows in another route than that of the basic mild.

Their substantial harm threshold and great thermal balance make them appropriate for use in superior-electrical power laser devices, although their huge transparency range enables them to operate having a wide number of laser wavelengths.

These Attributes make BBO crystals hugely attractive in different purposes, from laser frequency conversion to electro-optic modulation. Their large transparency array allows them to work by using a wide array of laser wavelengths, though their high hurt threshold makes sure they might deal with substantial-electrical power laser beams without the need of degradation.

Now Review the here most Electricity density to that which happens to be specified since the LIDT with the optic. Should the optic was tested at a wavelength apart from your working wavelength, the hurt threshold have to be scaled properly [three].

With appropriate care and managing, BBO crystals can past for many years. Nonetheless, their lifespan is usually shortened by factors such as higher temperature, humidity, and physical destruction. BBO crystals are strong and durable, but Like every optical element, they will degrade after some time if not appropriately cared for.

As will likely be mentioned under, there is a concentrating numerical aperture (NA) limitation towards the SHG stage-matching process just analogous on the spectral section matching limitation talked about within the past section (

Beta Barium Borate (BBO) crystals have taken the planet of photonics by storm. One of the more spectacular components of these crystals is their pioneering position in 266nm technology.

The length from the crystal is a crucial parameter to contemplate when optimizing the SHG system for that parameters of certain input pulses. Absent phase-matching and temporal wander-off effects, the SHG output increases exponentially with crystal duration. The intention when picking an SHG crystal should be to equilibrium the crystal length with the constraints based on the basic pulse. Reducing the crystal thickness minimizes consequences connected with both equally stage-matching bandwidth constraints and temporal walk-off, that are straight relevant.

And finally, spectroscopy, the analyze of interactions among matter and electromagnetic radiation, considerably Positive aspects from the 266nm technology. In spectroscopic programs, different wavelengths of sunshine interact in a different way with elements, supplying a spectrum that can be analyzed to ascertain the fabric’s Qualities or composition.
