Sometimes, the mismatch could be smaller. As an example, each time a β-BBO crystal is utilized to frequency double 1550 nm mild and supply 775 nm light-weight, the group velocity mismatch is just a few femtoseconds per millimeter.
Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our merchandise�?nonlinear conversion performance and also section-matching angle for a presented input wavelength and sign/idler wavelengths.
A1: Yes, BBO crystals Use a substantial problems threshold, producing them well suited for superior-electricity laser techniques. Their potential to face up to superior laser intensities with out suffering from optical injury makes them a fantastic option for frequency conversion in higher-electric power lasers.
Now Evaluate the utmost Electrical power density to that which is specified since the LIDT for the optic. If the optic was examined at a wavelength in addition to your functioning wavelength, the injury threshold needs to be scaled appropriately [3].
As an alternative to the reference pulse electrical power spectrum comprising an apodization filter, within the spatial area the filter will be in NA. The angular domain apodization filter nonetheless, is just in a single-dimension defined with the airplane k and .
EKSMA Optics makes use of cookies to provde the most effective purchasing working experience. For those who continue to work with our companies, We'll believe that you agree to the usage of these cookies.
Their supremacy With this area is not just accidentally, but a results of their intrinsic and meticulously crafted properties.
Operation of nonlinear crystals at temperatures underneath space temperature (to attain section matching) is mostly problematic, as click here it may well cause condensation of water over the crystal surfaces If your bordering air is not very dry.
The team velocities of the basic and second harmonic pulses are different, regardless if stage-matched, as well as magnitude of the team velocity mismatch depends upon the crystal Attributes along with the optical frequencies inside the pulses.
For CPM, we Slash our items at an angle equivalent to no or 90 stages stressing one of many significant axes. For NCPM, we decreased our products at an angle based on Snell’s regulation:
We use Numerical Aperture (NA) to explain the extent of the angular written content. Ideally, the fundamental laser gentle might be collimated through the crystal, since collimated light resembles a group of rays aligned to the identical direction with the NA of zero.
The production of Beta-Barium Borate (BBO) crystals is a fancy and meticulous method that needs a higher amount of precision and expertise. This method, called the flux system, starts With all the planning of a mix of barium borate and barium fluoride.
The 266nm technology refers back to the creation of ultraviolet gentle which has a wavelength of 266 nanometers.
flux-grown KTP and RTP with its significant nonlinearity, also in variants with large grey tracking resistance
