This information dives deep into the advantages and one of a kind Houses of BBO crystal and its paramount importance in efficient frequency doubling and harmonics generation at 266nm.
Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our items�?nonlinear conversion effectiveness and also phase-matching angle for a presented enter wavelength and signal/idler wavelengths.
From a ray-product point of view, the propagation direction defines the orientation from the central (chief) ray in Determine 23. The SHG process is impacted through the number of angles around which incident light-weight propagates, mainly because light that's not parallel into the chief ray has diminished section-matching relative on the chief ray.
From the vast world of nonlinear optical crystals, BBO crystals stand out as pioneers, specifically in the realm of 266nm era.
Ordinarily, the crystal materials should have a higher optical transparency for all wavelengths associated �?for example, for pump, signal and idler within an optical parametric amplifier.
The calculation higher than assumes a uniform beam depth profile. You should now take into consideration hotspots from the beam or other non-uniform depth profiles and about work out a greatest electricity density.
Filters underneath or the shape at The underside may be used to aid merchandise lookup or make additional inquiries.
This exceptional blend makes certain that β-BBO crystal is actually a promising applicant for nonlinear optical purposes like frequency converters and optical parametric oscillators. In quantum optics, β-BBO crystal can deliver entangled photon pairs and 10-photon entanglement.
Physically, when the fundamental spectrum is perfectly in the reference pulse spectrum, the SHG pulse intensity profile will be the sq. of the elemental depth profile, successfully truncating the duration. This scenario is illustrated in Determine 20.
It is usually important to focus the incident light from the crystal for SHG apps, since economical technology of 2nd harmonic gentle calls for large peak intensities, which include 109 W/cm2. When using femtosecond pulses with average energies in the nanojoule variety, obtaining the expected peak intensities can need tiny focal places.
The efficiency from the SHG course of action decreases significantly as the basic beam diverges from its target, Considering that the pulse Vitality is distributed across a larger beam cross part.
Although the examination results are only agent of one coating operate, Thorlabs specifies injury threshold values that account for coating variances.
From the check here professional medical field, imaging stands out as on the list of important processes, performing to be a window in to the human human body. The precision and clarity provided by the 266nm era have revolutionized specified imaging treatments. This particular wavelength, when employed in imaging, can create sharp, large-resolution photos that help clinicians in figuring out minute abnormalities or modifications in tissue structures Which may or else be disregarded.
Optical parametric amplification (OPA): We use OPA to measure our parts�?nonlinear conversion performance and period-matching angle for the supplied enter wavelength and signal/idler wavelengths. We guarantee that our products and solutions fulfill the specs for OPA apps.
