Optical crystals can exhibit different styles of optical nonlinearities, that may be utilized in several means:
While the above mentioned method gives a very good guideline for LIDT values, remember to Speak to Tech Guidance If the wavelength differs from the required LIDT wavelength. When your electric power density is under the adjusted LIDT of your optic, then the optic ought to do the job for your personal software.
A1: Indeed, BBO crystals Have a very superior damage threshold, building them suited to significant-electric power laser devices. Their capacity to withstand significant laser intensities without the need of struggling from optical harm tends to make them an outstanding option for frequency conversion in higher-ability lasers.
BBO crystal continues to be essentially the most flexible nonlinear optical crystals owing to its unique mix of optical Homes (
The seed crystal is a little BBO crystal with a distinct positioning together one among its principal axes. The seed crystal is affixed to some turning rod that dips to the thaw surface area place.
Normal cleaning and proper storage can assist prolong the lifespan of BBO crystals. It’s also vital that you stay away from exposing the crystals to situations outside the house their specified working vary, as this can result in everlasting destruction.
When laser mild is focused into a place, the diameter in the beam waistline may be the focal place measurement, and the speed at which the light diverges from your beam midsection is associated with the Rayleigh range (zR).
We also gauge the enhanced pulses�?temporal pulse shape and spectral transmission capability. We Be certain that our products meet the requirements for OPCPA apps.
A5: Yes, BBO crystals have exceptional thermal stability and might preserve their Homes at area temperature. Consequently they may be Employed in a variety of environments devoid of requiring Exclusive temperature Management.
A3: Of course, BBO crystals have a large transparency assortment that extends into the ultraviolet spectrum. This would make them suitable for apps that call for ultraviolet light-weight, for example UV spectroscopy and UV laser units.
Hi, I was questioning if It really is possible for you to create a BBO crystal by using a custom coating at 532nm essential and 266nm second harmonic technology. Greatest, Ben
The spectrally narrowed SHG pulse spectrum is alleged to generally be apodized, considering that an impact of the fundamental pulse exceeding the utmost input bandwidth Restrict is definitely the elimination of the very best and lowest frequencies within the SHG pulse spectrum.
The angular information of a concentrated beam might be visualized by tracing rays from your lens to the focal place. Every ray drawn with the lens to your tightly focused place (Determine 23) helps make a unique angle (ψ) Together with the Main ray, as well as the number of angles increases Together with the NA. As being the number of angles increases further than the reference NA filter (or angular domain apodization filter width), the section-matching in the rays beyond the filter width diminishes for that reason reducing the SHG conversion efficiency of People rays.
This decreases the helpful communication sizing as well as lowers the conversion efficiency. Such as, BBO crystals have click here an angular stroll-off of regarding 38 mrad for SHG at 1064 nm wavelength, which has to try and do with 6 times bigger than KDP crystals.
