Optical parametric oscillation (OPO): We make use of OPO to determine our products�?nonlinear conversion overall performance and period-matching angle to get a supplied enter wavelength and sign/idler wavelengths. We make specified that our products meet the requirements for OPO purposes.
EKSMA Optics employs cookies to provide you with the very best purchasing encounter. When you proceed to use our providers, We are going to assume that you just agree to the use of these cookies.
The damage Assessment are going to be carried out on the same optic (purchaser's optic will not be weakened). Screening may perhaps lead to supplemental charges or direct times. Make contact with Tech Assist To learn more.
As a way to use the required CW harm threshold of an optic, it's important to find out the next:
Delving further in the prowess of BBO crystals, it’s obvious that they symbolize the forefront of recent photonics. Their wide transparency assortment not merely bestows them with versatility but in addition makes sure that they're appropriate with assorted light sources.
If the crystal surfaces remain “dirty�?right after the above cleansing treatments, the surfaces may need been weakened. Be sure to Get hold of us for rework in the crystals.
Figure 22: The diagram at the very best shows two pulses with distinctive Heart frequencies incident on a cloth. The team velocity hold off in between the pulses once they enter the fabric is zero.
In conclusion, BBO crystals are a captivating and adaptable substance which includes significantly advanced the sphere of optics and photonics. By being familiar with their Attributes and the way to take care of them, we could continue on to harness their possible and drive additional improvements in optical technologies.
The group velocities of more info the fundamental and second harmonic pulses are also unique, even though section-matched, along with the magnitude with the team velocity mismatch depends upon the crystal Homes and the optical frequencies from the pulses.
A3: Certainly, BBO crystals have a large transparency vary that extends into your ultraviolet spectrum. This tends to make them appropriate for programs that involve ultraviolet gentle, including UV spectroscopy and UV laser systems.
This property sets it besides linear optical supplies that don’t alter the frequency of sunshine passing via them. Such a distinguishing attribute sorts the inspiration to get a plethora of purposes that BBO can provide.
The spectrally narrowed SHG pulse spectrum is claimed for being apodized, considering the fact that an result of the elemental pulse exceeding the maximum enter bandwidth limit would be the removal of the very best and least expensive frequencies in the SHG pulse spectrum.
As will probably be discussed down below, You will find a focusing numerical aperture (NA) limitation to the SHG section-matching approach specifically analogous to the spectral period matching limitation reviewed in the former part (
Regardless of whether the crystal product or coating is not delicate to water, smaller drinking water droplets may possibly target laser radiation a lot more tightly than below regular operation, and so damage the crystal material.
