But BBO crystals stand resilient, making certain that devices keep on to function without hiccups, minimizing downtimes and guaranteeing Value-effectiveness In the long term.

A2: Indeed, extended publicity to humidity can degrade the optical functionality of BBO crystals. Humidity may result in h2o absorption to the crystal surface, which can influence its optical Homes.

When the Rayleigh assortment is a lot less than the crystal thickness, the gap more than which the beam is optimally intensive is fewer than the crystal thickness.

The SHG light is polarized from the XZ plane and is orthogonal to both the Eo plus the k-vector. As an alternative to decompose the polarization of the SHG light into Ex and Ez parts, the electrical industry is often called a unprecedented wave (E'e). The refractive index for this extraordinary wave, n'e, improvements as a perform of θ. n'e(θ) is often calculated using the equation in Figure 13. The ellipse defining the extraordinary index of refraction as a functionality of θ is really a conic portion on the index ellipsoid.

Even nicely underneath the edge for instant harm, some crystal resources exhibit a ongoing degradation throughout the utilized quantity, e.

The calculation earlier mentioned assumes a uniform beam intensity profile. You have to now take into consideration hotspots within the beam or other non-uniform intensity profiles and roughly compute a most electric power density.

Now Evaluate the most energy density to that that is specified since the LIDT to the optic. If the optic was analyzed at a wavelength besides your functioning wavelength, the read more problems threshold need to be scaled correctly.

the chemical sturdiness; e.g., some crystal resources are hygroscopic, Other folks bear chemical modifications when heated inside of a vacuum chamber for software of the dielectric coating

We also layer our merchandise with anti-reflection levels to minimize illustration losses on the crystal surfaces.

For the reason that dynamics of this process are remarkably subject to experimental parameters, it is tough to arbitrarily forecast the specific outcomes on the 2nd harmonic pulse. These effects can consist of back conversion, during which 2nd harmonic mild is converted back again to essential light-weight, and spectral narrowing from the SHG pulse.

When comparing an LIDT specified for the pulsed laser to your laser, it is important to grasp the next:

The spectrally narrowed SHG pulse spectrum is claimed to get apodized, considering that an result of the basic pulse exceeding the maximum enter bandwidth Restrict would be the removal of the best and most affordable frequencies from the SHG pulse spectrum.

As are going to be reviewed beneath, There's a focusing numerical aperture (NA) limitation to your SHG period-matching course of action just analogous on the spectral stage matching limitation mentioned from the prior section (

This is particularly critical in industries like semiconductors and micro-electromechanical systems (MEMS), the place even a slight mistake can render a element ineffective or produce important losses. With BBO’s 266nm technology, industries can attain increased accuracy and dependability within their fabrication procedures, driving innovation and products top quality to new heights.
