If you don't locate the ideal products previously mentioned, you could let's know your necessities or purposes in the shape below. Our revenue or technical staff members will get again for you immediately.
Laser processing and substance managing: In the sphere of laser processing and materials dealing with, the substantial electricity capability of BIBO crystals would make them a crucial element in the manufacture of substantial energy density laser beams.
five mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The critical and noncritical phase matching LBO crystals are perfect for second or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
Crystal lifetime may also be strongly dependent on the fabric good quality, Despite the fact that selected degradation phenomena look like intrinsic limits of the material.
Both equally have a comparatively lower destruction threshold, but usually do not must be operated at significant intensities because of their significant nonlinearity. They may have an inclination for photorefractive consequences, which are harmful for frequency conversion, but are useful for, e.g., holographic knowledge storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive hurt�?is dependent strongly on the material composition; e.g. it might be lessened by way of MgO doping and by utilizing a stoichiometric composition.
Even when the crystal material or coating just isn't sensitive to water, modest water droplets could concentrate laser radiation much more tightly than under ordinary Procedure, and thus destruction the crystal substance.
At this time, as A form of fantastic nonlinear second harmonic crystal, it can be used to supply large effectiveness crystal of green or blue laser.
Procedure of nonlinear crystals at temperatures underneath home temperature (to achieve phase matching) is usually problematic, as it might cause condensation of drinking water within the crystal surfaces Should the bordering air isn't pretty dry.
rystal floor is horizontal and a bit earlier mentioned your fingers. Take a fresh, clean up sheet of lens tissue and place it over the crystal. Be sure the lens tissue may be drawn over the crystal floor. Up coming, place a little fall of pure isopropyl Liquor (IPA) on the lens tissue along with the crystal area.
the chemical sturdiness; e.g., some crystal resources are hygroscopic, Many others undertake chemical variations when heated in a vacuum chamber for software of the dielectric coating
) to blow off dust along with other loose contaminants initial. If a dry nitrogen line is accessible inside the lab, an air gun may also be utilized to blow absent dust particles. Blow from the surface area gently. Will not blow off the crystal itself from your hand!
This combination can make BIBO crystal exceptionally suited to harnessing the phenomenon of second harmonic era (SHG) within just stable-condition lasers and laser diodes.
Optical crystals can exhibit distinct varieties of optical nonlinearities, that may be used in numerous strategies:
Our crystals are used in an array of programs, such as numerous sorts of nonlinear frequency conversion and electro-optics, but check here in addition quantum know-how.
