Optical parametric oscillation (OPO): We use OPO to ascertain our objects�?nonlinear conversion efficiency and period-matching angle for your offered enter wavelength and signal/idler wavelengths. We make selected that our items meet up with the requirements for OPO programs.
The choice with the most suitable crystal materials to get a supplied software is usually far from trivial; it should require the thought of numerous features. By way of example, a higher nonlinearity for frequency conversion of ultrashort pulses does not assistance If your interaction size is strongly constrained by a big group velocity mismatch as well as minimal destruction threshold boundaries the relevant optical intensities.
Finally, the huge-angle tunability of BBOs facilitates customization like under no circumstances just before. According to the distinct demands of an software, the crystal might be modified with precision, making sure the output is always optimized.
Determine 23: This diagram illustrates a beam's focal region inside a uniaxial birefringent material. Straight traces, symbolizing rays, are drawn through the Middle on the beam midsection. Given that the beam diverges from the beam midsection, the energy inside the beam is dispersed in excess of a larger cross sectional location.
Superior-excellent crystals will likely have less defects and provide greater effectiveness, whilst a dependable provider will stand powering their items and offer you support when wanted. Very good customer support could also make the getting procedure smoother and much more pleasing.
Substantial hurt threshold: BBO crystals have superior destruction restrictions that could rise up for their high top rated and typical ability with out degradation or harm.
The next harmonic frequency wave is produced as a unprecedented wave, which happens to be polarized orthogonal to BBO Crystal the basic-frequency normal wave.
BBO crystals are used in a big range of applications because of their Remarkable optical properties. They are commonly Utilized in laser devices for frequency conversion, together with next, 3rd, and fourth harmonic technology. This allows with the manufacture of laser light at diverse wavelengths from one input wavelength.
We also layer our items with anti-reflection layers to decrease illustration losses within the crystal surfaces.
The phase matching angle may be altered by rotating the crystal round the y axis. An adjustment that is usually inside a handful of levels can both enhance the effectiveness of your crystal in the set up or match One more fundamental frequency while in the crystal's operating selection.
No matter whether it’s in the event of extra effective lasers, the exploration of quantum phenomena, or the generation of latest optical units, BBO crystals will definitely continue on to Perform a pivotal part.
As illustrated in the following table, the shorter the crystal, the wider the reference pulse spectrum. The desk underneath assumes a basic center wavelength inside the around-IR.
The magnitude of the effective nonlinear coefficient relies on the nonlinear tensor factors and to the utilized phase-matching configuration. A significant nonlinearity is very important particularly When the achievable optical intensities are lower.
Optical parametric amplification (OPA): We use OPA to evaluate our pieces�?nonlinear conversion performance and stage-matching angle to get a delivered input wavelength and signal/idler wavelengths. We guarantee that our products meet the specs for OPA applications.
