This short article dives deep into the benefits and special Homes of BBO crystal and its paramount importance in productive frequency doubling and harmonics technology at 266nm.
Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our products�?nonlinear conversion efficiency and section-matching angle to get a specified enter wavelength and sign/idler wavelengths.
Thorlabs provides a big choice of optics optimized to be used with femtosecond and picosecond laser pulses. Be sure to see below To find out more.
One of the defining qualities of BBO crystals is their higher problems threshold. Because of this they're able to endure significant amounts of laser electricity with no encountering degradation or destruction.
The seed crystal is a little BBO crystal with a definite positioning together among its principal axes. The seed crystal is affixed into a turning rod that dips in to the thaw area place.
In the case of Variety-I section matching and β-BBO crystals, the fundamental light-weight propagates as a rare wave while in the crystal, when the next harmonic gentle propagates as a standard wave.
Temperature level sensitivity: BBO crystals temperature sensitivity has an effect on their refractive indices and likewise phase-matching issues. This needs temperature amount stabilizing or tuning instruments to keep the best possible effectiveness.
the chemical sturdiness; e.g., some crystal elements are hygroscopic, Many others bear chemical alterations when heated inside a vacuum chamber for application of the dielectric coating
The lifespan of BBO crystals will vary greatly based on several elements. These incorporate how the crystals are made use of, how They're managed, as well as the problems wherein These are stored.
To circumvent this, BBO crystals needs to be stored within a dry natural environment and correctly sealed when not in use. Additionally, any cleansing course of action needs to be accompanied by complete drying to remove any residual humidity.
Additionally, the structural and compositional characteristics of BBO give it with impressive thermal security and resistance versus environmental troubles.
The event selling price depends on the temperature gradient, rotation charge, pulling rate, soften make-up, and oxygen pressure. We thoroughly keep track of these variables all through the development process to guarantee the uniformity and good quality of your boule.
Consequently, more info the 2nd harmonic pulse spectrum, revealed on the best, incorporates a spectral width roughly similar to the ideal circumstance. Preferably, each individual frequency in the basic pulse spectrum could be concurrently section matched.
Optical parametric amplification (OPA): We use OPA to measure our items�?nonlinear conversion general performance and phase-matching angle to get a supplied input wavelength and signal/idler wavelengths. We promise that our products and solutions meet the specs for OPA applications.
