Inertness to Moisture: BIBO crystal is inert to humidity, which implies it does not degrade or shed its optical Houses when subjected to humidity. This helps make BIBO a far more stable and dependable choice for optical applications in various environments.
Kingwin Optics provides significant-top quality BIBO crystal with Innovative coatings and mounting options, rendering it a great choice for researchers, engineers, and makers seeking economical and responsible nonlinear optical parts.
Inspect the crystal surface area for dust and stains by Keeping it around a dazzling seen-gentle supply. Viewing at distinct angles may also help see scattering from dust and stains. The crystal surface has to be cleaned as described below if dust and stains are uncovered.
With a large successful nonlinear coefficient, large hurt threshold, and inertness to moisture, BIBO crystal offers various rewards about other nonlinear optical supplies for example LBO and BBO.
Also, it could be hugely appealing to work with a crystal substance which may be critically section-matched at place temperature because noncritical stage matching typically involves the Procedure of your crystal inside a temperature-stabilized crystal oven. Even so, the feasibility of significant section matching may very well be specified just for sufficiently significant peak powers.
Dust and stains on crystal surfaces may cause scattering/reduction of sunshine and may even react with light-weight to wreck optical surfaces at a substantial incident laser energy.
The choice in the most suitable crystal content for your provided application is often considerably from trivial; it need to require the thing to consider of numerous facets. Such as, a large nonlinearity for frequency conversion of ultrashort pulses does not support In case the conversation length is strongly minimal by a large team velocity mismatch plus the reduced hurt threshold limits the applicable optical intensities.
Bismuth Triborate (BiB3O6 or BIBO) is actually a newly produced nonlinear optical crystal. It possesses large effective nonlinear coefficient, large injury threshold and inertness with respect to dampness.
In the case of ultrashort pulses the superior team velocity mismatch enforces using a shorter crystal, which demands substantial optical intensities for a provided conversion efficiency.
Crystals which might be non-critically section-matched in a crystal oven might exhibit troubles in the event the crystal temperature is altered way too promptly or way too usually. In particular, anti-reflection coatings may be ruined resulting from distinct thermal growth coefficients with the concerned materials.
In several scenarios, a nonlinear crystal employed for nonlinear frequency more info conversion has a really very long life time, that is for a longer period than that of The entire laser program. The crystal materials is essentially not modified through operation. Having said that, a diminished crystal lifetime can happen underneath several circumstances:
China BIBO crystals can be used not simply as higher-efficiency frequency doubling and frequency summing gadgets, but even have wide software prospects in the field of optical parametric oscillation (OPO), and What's more, it has a very important software inside the effective technology of ultrabright entangled photons via blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
The magnitude from the powerful nonlinear coefficient is dependent upon the nonlinear tensor elements and around the utilized phase-matching configuration. A significant nonlinearity is vital particularly If your achievable optical intensities are small.
Significant Injury Threshold: BIBO crystal features a significant harm threshold, making it possible for it to withstand substantial laser power with out suffering harm. This characteristic will make BIBO well suited for use in substantial-electrical power laser devices.
