In some instances, the mismatch could be little. One example is, every time a β-BBO crystal is accustomed to frequency double 1550 nm gentle and provide 775 nm mild, the group velocity mismatch is just a few femtoseconds for each millimeter.
The choice on the most fitted crystal material for the given application is often much from trivial; it need to involve the thing to consider of numerous elements. One example is, a significant nonlinearity for frequency conversion of ultrashort pulses isn't going to aid If your conversation length is strongly constrained by a considerable group velocity mismatch and also the reduced problems threshold restrictions the relevant optical intensities.
We diminished our boule into smaller sized things In keeping with buyer requirements employing a ruby blade, or wire noticed machine. Following that, polish these parts employing ruby powder or slurry on cast iron or copper plates.
) is The true secret for BBO to acquire high conversion efficiency. Restricted focus of laser beam will not be advisable.
Hygroscopic crystal materials deteriorate when they're not generally stored in sufficiently dry air (or even a dry purge gasoline). This applies e.g. to KDP and BBO, As well as in a lesser extent to LBO. It can be helpful to maintain this kind of crystal in a relatively elevated temperature, which makes it easier to preserve it dry.
EKSMA Optics uses cookies to provde the most effective purchasing working experience. For those who proceed to implement our expert services, we will think you agree to using these types of cookies.
Now compare the maximum electricity density to that that is specified since the LIDT to the optic. If your optic was examined in a wavelength other than your functioning wavelength, the harm threshold should be scaled correctly.
We also gauge the enhanced pulses�?temporal pulse shape and spectral transmission capacity. We Be sure that our solutions meet the necessities for OPCPA programs.
For purchaser benefit the crystals is usually mounted within an 1" anodized aluminum (Al) mount. The mounted crystals can be even further mounted in a standard 1" mirror mount being angle tuned for phase matching (as proven to the right). Drinking water-cooled mounts for high ability apps can be offered on ask for.
Although this rule of thumb offers a standard craze, It's not necessarily a quantitative Assessment of LIDT vs wavelength. In CW apps, By way of example, problems scales additional strongly with absorption while in the coating and substrate, which isn't going to always scale effectively with wavelength.
When comparing an LIDT specified for any pulsed laser towards your laser, it is crucial to be aware of the following:
rystal surface is horizontal and marginally previously mentioned your fingers. Have a contemporary, clean up sheet of lens tissue and put it about the crystal. Ensure that the lens tissue is often drawn through the crystal area. Next, location a small fall of pure isopropyl Liquor (IPA) within the lens tissue on top of the crystal surface.
The 266nm technology refers to the manufacture of ultraviolet light by using a wavelength of 266 nanometers.
On account of its fantastic Attributes BBO crystal has a variety of advantages for various apps, like NOPA with fsec pulses, harmonics era (around fifth) of Nd:YAG and Nd:YLF lasers, frequency doubling or tripling of femtosecond Ti:Sapphire and dye lasers, OPO at Sort 1 and kind more info two stage-matching, E/O switching for Pockels cells and many other.
