Hygroscopic crystal resources deteriorate when they're not normally saved in sufficiently dry air (or maybe a dry purge gasoline). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It may be useful to help keep this kind of crystal in a to some degree elevated temperature, which makes it much easier to continue to keep it dry.
Inertness to Humidity: BIBO crystal is inert to humidity, meaning it doesn't degrade or shed its optical Houses when subjected to humidity. This would make BIBO a more secure and reliable choice for optical purposes in a variety of environments.
The majority of the conventional nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation are offered from stock. Buyer-certain Proportions and AR coatings can also be presented at aggressive selling prices.
Crystal lifetime may also be strongly depending on the material quality, Even though selected degradation phenomena look like intrinsic limits of the material.
BIBO crystals can be used as substantial-performance frequency doubling and frequency summing gadgets and have broad software prospects in optical parametric oscillation (OPO).
GWU-Lasertechnik has a lot more than 30 several years of expertise in distributing laser crystals. Opt for GWU to get website pleasure from our vast awareness and in-discipline encounter!
Take note that whether or not the nominal intensity is underneath the nominal damage threshold, there may be troubles on account of fluctuations during the beam power or neighborhood intensity (e.g., if a beam profile has “very hot spots�?, or resulting from isolated defects in the crystal, which can be a lot more sensitive compared to standard crystal material.
Operation of nonlinear crystals at temperatures beneath home temperature (to attain period matching) is generally problematic, as it might result in condensation of drinking water over the crystal surfaces In the event the bordering air just isn't very dry.
In the case of ultrashort pulses the significant team velocity mismatch enforces the use of a shorter crystal, which involves significant optical intensities for any provided conversion efficiency.
Borates for example LBO and BBO also perform effectively in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Even perfectly down below the edge for fast damage, some crystal supplies exhibit a ongoing degradation throughout the made use of quantity, e.
China BIBO crystals can be employed don't just as significant-effectiveness frequency doubling and frequency summing units, but even have wide application prospective customers in the field of optical parametric oscillation (OPO), and Furthermore, it has an important software while in the successful era of ultrabright entangled photons through blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
The magnitude with the helpful nonlinear coefficient depends on the nonlinear tensor factors and within the used period-matching configuration. A significant nonlinearity is significant specifically In case the achievable optical intensities are low.
g. in the form of “gray tracking�? This sort of phenomena are specifically common for Procedure with ultraviolet mild. Observe that a gradual degradation can also guide into immediate catastrophic damage via excessive warmth technology.
