Hygroscopic crystal materials deteriorate when they are not always kept in adequately dry air (or even a dry purge gas). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It can be handy to help keep this kind of crystal in a to some degree elevated temperature, that makes it easier to retain it dry.
Inertness to Moisture: BIBO crystal is inert to moisture, which suggests it does not degrade or reduce its optical Homes when exposed to humidity. This tends to make BIBO a far more steady and reputable choice for optical purposes in many environments.

With a substantial helpful nonlinear coefficient, substantial hurt threshold, and inertness to humidity, BIBO crystal delivers many rewards in excess of other nonlinear optical elements including LBO and BBO.
BIBO crystals can be used as significant-performance frequency doubling and frequency summing devices and possess wide application potential customers in optical parametric oscillation (OPO).
Whether or not the crystal content or coating is just not delicate to drinking water, compact h2o droplets may emphasis laser radiation a lot more tightly than less than regular operation, and therefore damage the crystal materials.
Notice that whether or not the nominal depth is under the nominal damage threshold, there may be complications on account of fluctuations while in the beam power or regional intensity (e.g., if a beam profile has “very hot spots�?, or resulting from isolated defects in a crystal, which can be far more delicate in comparison to the regular crystal content.
And is especially useful for building wavelengths while in the inexperienced and blue spectrum by means of continuous-wave (CW) radiation. The elevated powerful nonlinearity of BIBO crystal not merely improves the performance with the SHG system but will also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser techniques.
They show fantastic homogeneity in excess of large volumes and possess a significant injury threshold, but are hygroscopic and have a very low nonlinearity.
Crystals that are non-critically stage-matched within a crystal oven could show difficulties in the event the crystal temperature is transformed far too speedily or as well normally. In particular, anti-reflection coatings can be harmed on account of diverse thermal growth coefficients of your concerned products.
) to blow off dust and other loose contaminants to start with. If a dry nitrogen line is available from the lab, an air gun may also be utilised to blow away dust particles. Blow off the area gently. Tend not to blow off the crystal itself out of your hand!
GWU-Lasertechnik provides all typical nonlinear crystals like LBO, BBO and KTP using a broad variety of technical specs. Beside the perfectly-founded resources, progressive crystals like CLBO or BiBO with outstanding Attributes for e. g. deep-UV technology or substantial-electrical power ultrashort pulse lasers are available. No matter if unique parts for R & D functions are demanded or Expense-economical quantities in little, medium or massive batches with in-time delivery for your output line are needed: GWU’s focused company helps you to discover read more the ideal core elements on your application.
linear absorption, which may bring about heating at significant optical electrical power stages, so the stage matching is disturbed, and thermal lensing might take place
Because the 2nd harmonic (SHG) may be commonly accustomed to generate coherent obvious light and ultraviolet radiation, persons concentrate to it, but the normal nonlinear crystals which include KDP, LBO, KTP, B-BBO even have several shortcomings. BIBO crystal is a whole new style of nonlinear crystal. When compared with KDP crystal, it would make up with the drawback that KDP crystal can expand in significant measurement but dissolve in water.
