BBO Crystal Things To Know Before You Buy

Optical parametric oscillation (OPO): We make use of OPO to find out our products�?nonlinear conversion general performance and phase-matching angle for any given input wavelength and sign/idler wavelengths. We make certain that our merchandise satisfy the necessities for OPO purposes.
When the above mentioned procedure provides a fantastic guideline for LIDT values, make sure you Get hold of Tech Guidance In case your wavelength is different from the specified LIDT wavelength. In the event your energy density is lower than the adjusted LIDT with the optic, then the optic must perform for your personal application.
And lastly, the broad-angle tunability of BBOs facilitates customization like hardly ever prior to. Depending on the distinct requirements of an software, the crystal may be altered with precision, making sure the output is usually optimized.
Figure 23: This diagram illustrates a beam's focal area within a uniaxial birefringent material. Straight strains, symbolizing rays, are drawn from the Heart of your beam midsection. Given that the beam diverges from the beam waistline, the Vitality inside the beam is distributed above a larger cross sectional location.
Following extraction, the BBO crystals are then Slice into the specified sizes and shapes. This cutting approach is executed with precision instruments to make sure that the crystals are Lower properly and cleanly.
Remember to select your transport country to perspective probably the most accurate inventory details, and to find out the correct Edmund click here Optics income Business office to your order.
Temperature degree sensitivity: BBO crystals temperature sensitivity has an effect on their refractive indices and also period-matching troubles. This requires temperature level stabilizing or tuning instruments to keep ideal effectiveness.
When pulse lengths are among 1 ns and 1 µs, laser-induced damage can come about either because of absorption or perhaps a dielectric breakdown (as a result, a user should Verify both of those CW and pulsed LIDT). Absorption is both due to an intrinsic assets of your optic or because of surface area irregularities; Hence LIDT values are only legitimate for optics Assembly or exceeding the floor good quality requirements offered by a manufacturer.
The spatial stroll-off angle relies on the scale in the beam and the crystal duration. Whilst the angle can be sizeable, it is normally smaller, ordinarily on the purchase of 10 mrad, and may be neglected.
A: The broad transparency vary gives flexibility, permitting BBO crystals to be used throughout a various number of wavelengths and programs.
Pumped by the fourth harmonic of the Nd:YAG laser (at 266nm), a tunable OPO with sign wavelength selection concerning 422nm and 477nm has actually been noticed by angle-tuning a sort I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields greater than 50µJ (optimum a hundred thirtyµJ),
This enhancement in clarity may result in early analysis and timely intervention, potentially preserving life and improving upon patient outcomes.
When an input pulse's spectral vary is equivalent to or narrower when compared to the reference pulse, the produced 2nd harmonic pulse provides a period that's shorter by a factor of 1/√2 and also a spectral width that is certainly broader by a factor of √2.
Some manufacturers' SHG crystals, which includes Thorlabs', provide in the vicinity of-period-matched ailments for Typically incident enter mild for a specified elementary frequency. These producers polish the faces with the SHG crystals this sort of which the angle among the Ordinarily incident light-weight and the optic axis would be the stage-matched angle for the specified frequency.
