The susceptibility to moisture of BiBO may be very reduced. Having said that, people are recommended to provide dry problems for both of those use and storage of BiBO to lengthen the life span. Drinking water condensation on crystal surfaces needs to be Totally averted Anytime.
Inertness to Dampness: BIBO crystal is inert to dampness, which implies it does not degrade or drop its optical properties when subjected to humidity. This helps make BIBO a more steady and trustworthy selection for optical purposes in various environments.
five mm to minimize team velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The crucial and noncritical phase matching LBO crystals are ideal for next or third harmonic generation of Nd:YAG and Yb:doped lasers.
Ordinarily, the crystal material ought to have a high optical transparency for all wavelengths involved �?for example, for pump, signal and idler in an optical parametric amplifier.
BIBO crystals can be used as large-efficiency frequency doubling and frequency summing products and also have wide application prospective buyers in optical parametric oscillation (OPO).
Even when the crystal product or coating is just not delicate to water, compact h2o droplets may well concentration laser radiation a lot more tightly than less than standard operation, and thus hurt the crystal product.
The selection from the best click here suited crystal product for any given application is usually considerably from trivial; it must require the thing to consider of numerous aspects. By way of example, a large nonlinearity for frequency conversion of ultrashort pulses will not assist if the interaction length is strongly limited by a considerable group velocity mismatch plus the minimal problems threshold limitations the relevant optical intensities.
And is particularly useful for generating wavelengths during the green and blue spectrum through steady-wave (CW) radiation. The elevated productive nonlinearity of BIBO crystal not just improves the performance of your SHG procedure but will also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser programs.
They exhibit great homogeneity more than large volumes and also have a substantial harm threshold, but are hygroscopic and possess a reduced nonlinearity.
Numerous Houses of a nonlinear crystal might be essential for an software e.g. in nonlinear frequency conversion:
Even well down below the brink for instant hurt, some crystal supplies exhibit a ongoing degradation throughout the made use of volume, e.

Optical crystals can exhibit various styles of optical nonlinearities, which can be used in many means:
flux-grown KTP and RTP with its significant nonlinearity, also in variants with substantial grey monitoring resistance
