The 5-Second Trick For BBO Crystal
Blog Article
Crystals which can be non-critically period-matched within a crystal oven may well exhibit problems in the event the crystal temperature is adjusted much too quickly or far too often. In particular, anti-reflection coatings may very well be ruined as a result of distinct thermal enlargement coefficients from the involved elements.
The realm of material processing has equally benefited with the precision of 266nm era. State-of-the-art microfabrication procedures, which require intricate detailing on products at a microscopic level, need an exact mild supply. The sharpness connected to the 266nm wavelength ensures that lasers could make specific cuts, etches, and modifications.
A1: Certainly, BBO crystals Have a very superior destruction threshold, making them suited to substantial-energy laser devices. Their capacity to resist large laser intensities without the need of struggling from optical damage can make them an excellent choice for frequency conversion in high-ability lasers.
Borates including LBO and BBO also work nicely in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Next harmonic technology (SHG): We utilize SHG to evaluate our products�?nonlinear conversion performance and phase-matching angle for your specified enter wavelength. We promise that our goods fulfil the necessities for SHG purposes.
The team velocity may be the pace of the heartbeat, or maybe more formally the envelope of the electric industry. The group index equally governs BBO Crystal the velocity from the envelope relative into the velocity of light inside of a vacuum and is particularly dependent on the dispersion of the fabric.
The cutting angle is dependent upon the popular phase-matching problem for frequency conversion purposes. Phase matching describes matching the period speeds of assorted beams connected to nonlinear procedures so that they Create up constructively more than fars away Within the crystal.
g. twenty μm. The group velocity mismatch during the thicker substrate substance might not matter, given that the nonlinear conversation can take spot only in The skinny crystal. The substrate only serves to mechanically stabilize The skinny nonlinear crystal.
Each aspect of BBO, from its atomic construction to its wide application spectrum, underscores its pivotal part in modern-day science and engineering.
The period matching angle is often altered by rotating the crystal round the y axis. An adjustment that is often in just a number of degrees can both optimize the functionality on the crystal while in the setup or match Yet another fundamental frequency in the crystal's functioning array.
When evaluating an LIDT specified for a pulsed laser towards your laser, it is vital to learn the subsequent:
The crystal axis is c. The Main ray is parallel for the path utilized to evaluate the tuning angle (θ), which can be optimized through phase matching. Conversion performance is optimized for rays parallel to the Main ray and worse for rays at larger sized angles (ψ) on the chief ray.
When an input pulse's spectral variety is equal to or narrower compared to reference pulse, the produced next harmonic pulse has a period that is shorter by an element of one/√two and a spectral width that's broader by a factor of √two.
flux-developed KTP and RTP with its higher nonlinearity, also in variants with significant gray monitoring resistance
