The calculation higher than assumes a uniform beam intensity profile. You have to now look at hotspots inside the beam or other non-uniform intensity profiles and around compute a optimum energy density.
Sadly, it may be very hard to check the LIDT specification of the optic on your laser. You will find various regimes where a pulsed laser can injury an optic and this relies within the laser's pulse size. The highlighted columns from the table under define the pertinent pulse lengths for our specified LIDT values.
Hello, thanks for calling Thorlabs. The wavelength ranges of your antireflective coatings on these β-BBO crystals align Together with the respective wavelength bands that these crystals are optimized for. Requests for customizations may be produced by achieving out to us at techsupport@thorlabs.com
When one of those β-BBO Crystals is mounted from the RSP1 mount, the crystal will likely be centered over the eight-32 (M4) hole inside the mount's base with no need to have for spacers.
BBO crystals could be cleaned using a delicate cloth or air blower. For stubborn stains, a mild detergent or isopropyl Alcoholic beverages can be used. It’s important to steer clear of utilizing abrasive products that would scratch the crystal’s area. When cleansing BBO crystals, it’s crucial that you use a delicate, round motion to avoid scratching the floor.
Provided these purposes, it’s apparent why BBO, with its inherent capacity to efficiently create the 266nm wavelength, is so highly prized. The crystal’s one of a kind nonlinear optical Houses empower the conversion of other wavelengths into the coveted 266nm gentle, ensuring that scientists and industries have use of this vital Software.
In some cases, the mismatch could be small. By way of example, when a β-BBO crystal is used to frequency double 1550 nm light-weight and provide 775 nm mild, the group velocity mismatch is only some femtoseconds for every millimeter.
These properties make BBO crystals really desirable in a variety of purposes, from laser frequency conversion to electro-optic modulation. Their huge transparency array enables them to work having a broad variety of laser wavelengths, while their substantial damage threshold makes sure they could cope with large-power laser beams without degradation.
Now Review the most Vitality density to that and that is specified as the LIDT to the optic. In case the optic was analyzed in a wavelength other than your running wavelength, the harm threshold needs to be scaled properly [3].
Regular cleansing and right storage can assist prolong the lifespan of BBO crystals, ensuring their ongoing contribution to the field of optics and photonics.
The group velocity as well as the stage velocity are usually not equivalent, that means the sine wave of the copyright as well as the envelope of the pulse move via optical media at unique speeds.
This characteristic interprets to lowered have to have for substantial thermal administration units, once more accentuating Value cost savings and technique simplicity.
When laser mild is concentrated to a place, the diameter with the beam waist would be the focal spot dimension, and the rate at which the light diverges through the beam waistline is relevant to the Rayleigh selection (zR).
BBO’s versatility definitely shines when a person considers the breadth of its apps. It’s not click here merely confined to at least one specialized niche of photonics but stretches throughout various domains. Consider frequency doubling, for instance. In this process, photons Along with the identical frequency Incorporate throughout the crystal to create new photons with double the frequency of the original.
