Occasionally, the mismatch might be tiny. For instance, every time a β-BBO crystal is utilized to frequency double 1550 nm gentle and provide 775 nm mild, the team velocity mismatch is only some femtoseconds for each millimeter.
Hi, thank you for making contact with Thorlabs. The wavelength ranges of the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations can be made by reaching out to us at techsupport@thorlabs.com
Sadly, it might be very hard to check the LIDT specification of an optic to the laser. There are several regimes through which a pulsed laser can injury an optic and this relies about the laser's pulse size. The highlighted columns within the desk underneath define the suitable pulse lengths for our specified LIDT values.
Take note that even when the nominal depth is below the nominal injury threshold, there may be challenges as a result of fluctuations inside the beam power or nearby depth (e.g., if a beam profile has “hot places�?, or as a consequence of isolated defects inside of a crystal, that happen to be more sensitive compared to frequent crystal product.
Wide openness variety: BBO crystals have a large openness array from 189 nm to 3500 nm, covering ultraviolet, noticeable, and around-infrared regions. This permits BBO crystals to be used for numerous laser resources with various wavelengths.
This sort of resilience ensures that its nonlinear Attributes aren't conveniently compromised, making it a favourite in environments where by consistency and trustworthiness are paramount.
Be sure to Observe that Now we have a buffer constructed in between the required damage thresholds online and the assessments which Now we have accomplished, which accommodates variation between batches. On ask for, we can provide individual take a look at information and also a testing certification.
BBO crystals are utilized inside of a big range of purposes because of their Fantastic optical Qualities. They are commonly used in laser methods for frequency conversion, such as 2nd, 3rd, and fourth harmonic technology. This allows for the creation of laser light at distinct wavelengths from an individual input wavelength.
A5: Of course, BBO crystals have outstanding thermal balance and can manage their properties at home temperature. This means that they can be Utilized in a wide range of environments without the need of necessitating Exclusive temperature Handle.
GWU-Lasertechnik features all typical nonlinear crystals like LBO, BBO and KTP having a wide assortment of specifications. Beside the very well-proven materials, modern crystals like CLBO or BiBO with excellent Qualities for e. g. deep-UV technology or large-power ultrashort pulse lasers can be obtained. Regardless click here of if specific parts for R & D functions are demanded or Price tag-economical numbers in modest, medium or big batches with in-time shipping and delivery for that output line are necessary: GWU’s devoted provider really helps to locate the best core parts to your software.
When comparing an LIDT specified for the pulsed laser to the laser, it is important to understand the following:
The posture in the environmentally friendly curve is dependent upon θ. In such a case, the angle θ continues to be tuned to offer a refractive index for 515 nm light that matches the refractive index for 1030 nm mild. This tuning angle is thus optimized for Style-I SHG phase matching plus a elementary-frequency input beam of 1030 nm.
In the healthcare discipline, imaging stands out as among the list of critical procedures, performing for a window to the human overall body. The precision and clarity provided by the 266nm generation have revolutionized particular imaging strategies. This unique wavelength, when used in imaging, can develop sharp, significant-resolution photographs that assist clinicians in determining moment abnormalities or variations in tissue buildings That may in any other case be missed.
This helps make them really sturdy and resilient, even further maximizing their suitability for demanding optical purposes.
