If you do not find the ideal products and solutions above, it's possible you'll let's know your prerequisites or applications in the form underneath. Our gross sales or specialized workers will get back to you without delay.
Inertness to Humidity: BIBO crystal is inert to moisture, meaning it doesn't degrade or reduce its optical properties when exposed to humidity. This would make BIBO a more steady and responsible option for optical applications in a variety of environments.
Most of the regular nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation are offered from stock. Consumer-unique dimensions and AR coatings may also be offered at aggressive rates.
By distributing the knowledge, you give your consent on the probable publication of your respective inputs on our Web page according to our principles. (When you afterwards retract your consent, We'll delete Those people inputs.) As your inputs are first reviewed because of the author, They might be revealed with some hold off.
BIBO crystals can be employed as significant-performance frequency doubling and frequency summing units and have wide software prospective clients in optical parametric oscillation (OPO).
Dust and stains on crystal surfaces could potentially cause scattering/loss of sunshine and can even react with light to wreck optical surfaces in a significant incident laser electrical power.
The selection of your best suited crystal substance to get a provided software is commonly considerably from trivial; it must contain the thought of many factors. Such as, a high nonlinearity for frequency conversion of ultrashort pulses won't aid When the conversation length is strongly confined by a sizable group velocity mismatch as well as the low damage threshold restrictions the applicable optical intensities.
Operation of nonlinear crystals at temperatures beneath room temperature (to obtain stage matching) is usually problematic, as it might result in condensation of water over the crystal surfaces If your encompassing air isn't very dry.
They show excellent homogeneity around huge volumes and possess a higher problems threshold, but are hygroscopic and have a minimal nonlinearity.
Extreme optical intensities in the course of operation might immediately damage a crystal. Unfortunately, nonlinear crystals often should be operated not significantly from their optical injury threshold to attain a sufficiently click here superior conversion effectiveness. This implies a trade-off between conversion performance and crystal life time.
Even nicely down below the edge for fast damage, some crystal resources exhibit a ongoing degradation throughout the made use of volume, e.
This combination makes BIBO crystal exceptionally suited for harnessing the phenomenon of 2nd harmonic era (SHG) in solid-state lasers and laser diodes.
The magnitude of your successful nonlinear coefficient will depend on the nonlinear tensor elements and within the used phase-matching configuration. A high nonlinearity is essential specifically If your achievable optical intensities are minimal.
Considering the fact that the next harmonic (SHG) could be extensively utilized to crank out coherent visible light-weight and ultraviolet radiation, persons listen to it, but the standard nonlinear crystals like KDP, LBO, KTP, B-BBO even have several shortcomings. BIBO crystal is a new type of nonlinear crystal. When compared with KDP crystal, it will make up with the drawback that KDP crystal can develop in huge dimension but dissolve in water.
