Optical crystals can exhibit different types of optical nonlinearities, which can be used in many techniques:
In lots of situations, a nonlinear crystal useful for nonlinear frequency conversion has an exceptionally very long life time, which can be for a longer time than that of The entire laser procedure. The crystal product is basically not modified in the course of operation. Nevertheless, a lowered crystal life time can manifest beneath several instances:
Equally have a relatively very low problems threshold, but will not need to be operated at superior intensities because of their large nonlinearity. They have a tendency for photorefractive outcomes, which might be harmful for frequency conversion, but are utilized for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive destruction�?relies upon strongly on the material composition; e.g. it can be decreased through MgO doping and through the use of a stoichiometric composition.
The overall performance of BBO crystals might be influenced by various elements. The caliber of the crystal itself is paramount, as defects or impurities can degrade its optical Houses. The temperature at which the crystal operates can also have an effect on its effectiveness, as adjustments in temperature can result in thermal enlargement or contraction, potentially altering the crystal’s optical Homes.
For beams with a superior PRF both equally the standard and peak powers has to be when compared to the equal CW electricity. Furthermore, for remarkably clear elements, There is certainly minor to no fall in the LIDT with raising PRF.
Beta-Barium Borate, often called BBO crystals, are a novel style of nonlinear optical crystal which have attained substantial recognition in the sphere of optics and photonics. These crystals are renowned for their comprehensive transparency assortment, which extends through the ultraviolet to your in the vicinity of-infrared spectrum.
Filters below or the form at The underside can be employed to assist product or service research or make additional inquiries.
The vast majority of our standard crystals occur mounted into open ring holders. Remember to Be aware the letter "H" while in the item code which implies that crystal is supplied mounted.
Each individual aspect of BBO, from its atomic framework to its broad software spectrum, underscores its pivotal purpose in modern-day science and technology.
Modest acceptance angle: BBO crystals have a little acceptance angle that limits the enter light beam’s mild beam divergence and top rated method top quality for effective regularity conversion.
BBO crystals are renowned for his or her Outstanding optical Homes. Their extensive transparency array will allow them to operate successfully across a broad spectrum, from ultraviolet to in close proximity to-infrared light. This makes them extremely multipurpose and ideal for many different programs.

In the case of ultrashort more info pulses the substantial group velocity mismatch enforces the usage of a shorter crystal, which demands substantial optical intensities for a specified conversion performance.
As a result of its excellent properties BBO crystal has a variety of benefits for various applications, like NOPA with fsec pulses, harmonics generation (around fifth) of Nd:YAG and Nd:YLF lasers, frequency doubling or tripling of femtosecond Ti:Sapphire and dye lasers, OPO at Type 1 and Type 2 section-matching, E/O switching for Pockels cells and all kinds of other.
