This effectiveness is important, specially when 1 considers the technology on the 266nm wavelength, the place even slight inefficiencies may result in important Vitality losses.
This good-tuning ability signifies that BBO crystals can cater to both of those generic and hugely specialized requires with equal finesse.
Regrettably, it may be very hard to compare the LIDT specification of the optic to the laser. You will find various regimes where a pulsed laser can injury an optic which is based over the laser's pulse size. The highlighted columns in the desk underneath outline the applicable pulse lengths for our specified LIDT values.
Crystal lifetime can also be strongly depending on the fabric high-quality, Whilst specified degradation phenomena appear to be intrinsic limitations of the fabric.
Even perfectly underneath the edge for instant hurt, some crystal products exhibit a constant degradation throughout the utilised quantity, e.
A common technique for obtaining ultrathin crystals will be to initially optically contact a thicker nonlinear crystal with some substrate (e.g. of fused silica) after which to shine the crystal all the way down to the needed thickness of e.

Almost all of our conventional crystals come mounted into open up ring holders. Please note the letter "H" in the merchandise code which suggests that crystal is equipped get more info mounted.
Each aspect of BBO, from its atomic structure to its wide software spectrum, underscores its pivotal function in contemporary science and engineering.
It’s like having one Observe and splitting it into two harmonious tones. This process could be critical in numerous advanced optical experiments and systems.
Hi, I was wondering if It can be possible for yourself to produce a BBO crystal using a tailor made coating at 532nm elementary and 266nm next harmonic technology. Ideal, Ben
Exactly what are BBO Crystals? BBO crystals can be a sort of nonlinear optical crystal known for their large transparency selection, higher damage threshold, and superb thermal and chemical steadiness.
The 266nm generation refers to the production of ultraviolet light-weight having a wavelength of 266 nanometers.
This decreases the productive conversation size and likewise lowers the conversion success. Such as, BBO crystals have an angular stroll-off of concerning 38 mrad for SHG at 1064 nm wavelength, which has to complete with 6 occasions larger than KDP crystals.
