Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our merchandise�?nonlinear conversion performance as well as stage-matching angle for your offered input wavelength and signal/idler wavelengths.
The hurt Examination will probably be completed on an identical optic (customer's optic will not be ruined). Testing may well cause additional fees or guide instances. Contact Tech Assist for more information.
Crystal life span can also be strongly depending on the material top quality, Despite the fact that particular degradation phenomena appear to be intrinsic restrictions of the fabric.
Usually, the crystal substance should have a substantial optical transparency for all wavelengths concerned �?one example is, for pump, signal and idler within an optical parametric amplifier.
Phase matching noticeably increases the conversion performance and will be needed to get enough frequency-doubled mild for programs, but second harmonic era (SHG) will arise although stage matching is just not performed. The effect of stage matching around the output depth of SHG light-weight (I2ω) is illustrated in Determine 16.
The chopping angle is dependent upon the popular stage-matching problem for frequency conversion applications. Period matching describes matching the phase speeds of varied beams associated with nonlinear procedures so which they Construct up constructively over fars away Within the crystal.
We also gauge the improved pulses�?temporal pulse condition and spectral transmission capacity. We Be sure that our solutions satisfy the requirements for OPCPA programs.
The spatial walk-off angle is dependent upon the scale on the beam as well as crystal duration. Whilst the angle could be major, it is usually modest, ordinarily over the order of 10 mrad, and may be neglected.
It is often needed to emphasis the incident mild during the crystal for SHG applications, considering that efficient generation of next harmonic gentle necessitates superior peak intensities, for example 109 W/cm2. When employing femtosecond pulses with reasonable energies from the nanojoule assortment, acquiring the expected peak intensities can require smaller focal spots.
Hello, I was wondering if it's doable to suit your needs to generate a BBO crystal using a personalized coating at 532nm fundamental and 266nm 2nd harmonic generation. Finest, Ben
Additionally, BBO crystals may also be known for their substantial nonlinear coefficient, which permits them to effectively transform the frequency of sunshine.
The 266nm era refers to the manufacture of ultraviolet light using a wavelength of 266 nanometers.
Some brands' SHG crystals, which include Thorlabs', offer BBO Crystal near-stage-matched conditions for Commonly incident enter light to get a specified basic frequency. These manufacturers polish the faces in the SHG crystals this kind of the angle in between the Generally incident mild as well as optic axis would be the phase-matched angle for the specified frequency.
