But BBO crystals stand resilient, ensuring that techniques go on to operate with no hiccups, minimizing downtimes and making sure Expense-success In the long term.

Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our items�?nonlinear conversion performance and stage-matching angle for your provided input wavelength and signal/idler wavelengths.

The injury Investigation are going to be carried out on a similar optic (customer's optic will not be weakened). Testing may perhaps cause supplemental costs or guide periods. Speak to Tech Support To find out more.

Borates including LBO and BBO also function perfectly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.

For beams that has a large PRF both the typical and peak powers must be in comparison to the equivalent CW electrical power. Also, for really clear elements, There is certainly little to no drop in the LIDT with growing PRF.

Quite a few diverse stage-matching ways can be employed to equalize the refractive indices of the basic and 2nd harmonic gentle. One particular method, which makes use of linearly polarized gentle along with the difference between the ordinary and remarkable refractive indices, is Variety-I important phase matching. This can be a widespread strategy for unfavorable uniaxial crystals during which no > ne.

The next harmonic frequency wave is produced as an extraordinary wave, which can be polarized orthogonal to the basic-frequency ordinary wave.

A next issue is that the group velocity mismatch amongst the second harmonic and essential-frequency pulses will bring about one particular pulse lagging one other as The 2 propagate. This is known as temporal walk-off and will come about even under optimal section-matched ailments.

BBO crystals are fragile and require careful managing to circumvent damage to their surfaces. They must be managed with clear, lint-free of charge gloves to prevent scratching or contaminating their surfaces. When not in use, BBO crystals ought to be stored in the awesome, dry spot here from immediate daylight, as prolonged publicity to warmth and light can degrade their optical Attributes.

For CPM, we Minimize our pieces at an angle equivalent to no or 90 concentrations stressing among the major axes. For NCPM, we lowered our items at an angle determined by Snell’s regulation:

NCPM occurs if the input beam propagates at an angle aside from zero or 90 levels worrying one of many significant axes, such as the Z-axis. Its polarization is parallel to that axis, for instance Z-polarized.

As will be discussed beneath, there is a concentrating numerical aperture (NA) limitation to your SHG stage-matching procedure exactly analogous to your spectral stage matching limitation discussed during the preceding segment (

Inspect the crystal area for dust and stains by holding it around a dazzling noticeable-gentle supply. Viewing at distinctive angles can assist see scattering from dust and stains. The crystal area should be cleaned as described beneath if dust and stains are located.
