The level of the solvent might be adjusted for various crystal dimensions so the lens tissue is stored moist for the whole drag but there's not any visible trace of solvent about the crystal area following the drag is completed. Inspect the floor and repeat if required, but only use Every sheet of lens tissue when.
However, though BBO crystals can run at area temperature, Extraordinary temperatures need to nevertheless be prevented as they might influence the crystal’s stage-matching situations and potentially bring about hurt.
We lessened our boule into lesser merchandise In keeping with consumer specs using a ruby blade, or cord observed machine. Following that, polish these pieces working with ruby powder or slurry on Solid iron or copper plates.
The SHG gentle is polarized during the XZ plane and is also orthogonal to both the Eo as well as k-vector. Rather than decompose the polarization with the SHG light into Ex and Ez elements, the electric subject is usually referred to as a rare wave (E'e). The refractive index for this incredible wave, n'e, modifications as a purpose of θ. n'e(θ) could be calculated using the equation in Figure 13. The ellipse defining the amazing index of refraction being a operate of θ can be a conic part of your index ellipsoid.
BBO is of specific relevance during the noticeable and much UV. Lots of stage-matching programs are probable, including the next:
Substantial damage threshold: BBO crystals have higher injury limits which will stand up for their superior leading and typical electrical power without degradation or problems.
Now compare the maximum electric power density to that which is specified given that the LIDT with the optic. In the event the optic was tested in a wavelength other than your running wavelength, the problems threshold should be scaled properly.
Besides their use in laser frequency conversion, BBO crystals have discovered applications in electro-optic modulation and quantum optics experiments.
A: A superior harm threshold makes sure the crystal can deal with far more electric power check here without the need of degrading, leading to more time lifespan and reliable general performance.
A: The wide transparency assortment gives versatility, letting BBO crystals for use across a various variety of wavelengths and applications.
NCPM happens if the input beam propagates at an angle other than zero or ninety degrees stressing among the list of key axes, including the Z-axis. Its polarization is parallel to that axis, such as Z-polarized.
However, in several conditions, the primary difference in the basic and 2nd harmonic pulse velocities can result in one particular pulse to drastically lag another.
The magnitude with the successful nonlinear coefficient will depend on the nonlinear tensor elements and about the used period-matching configuration. A high nonlinearity is essential notably In the event the achievable optical intensities are minimal.
Optical parametric amplification (OPA): We use OPA to measure our pieces�?nonlinear conversion functionality and stage-matching angle to get a supplied enter wavelength and sign/idler wavelengths. We guarantee that our items fulfill the specs for OPA applications.
