Optical parametric oscillation (OPO): We use OPO to ascertain our products�?nonlinear conversion general performance and phase-matching angle for any given enter wavelength and sign/idler wavelengths. We make particular that our products satisfy the necessities for OPO applications.

Normal cleaning and appropriate storage will help increase the lifespan of BBO crystals, ensuring their ongoing contribution to the sector of optics and photonics.
Crystal lifetime can be strongly depending on the fabric good quality, Even though specific degradation phenomena appear to be intrinsic limits of the fabric.
As opposed to the reference pulse electrical power spectrum comprising an apodization filter, while in the spatial domain the filter will be in NA. The angular area apodization filter nevertheless, is only in a single-dimension described because of the airplane k and .
BBO crystals have two refractive indices: ne for incredible rays and no for normal rays. The difference between ne and no is determined by the wavelength of light as well as the crystal’s temperature.
β-BBO Crystal—a widely utilised nonlinear crystal for frequency conversion while in the ultraviolet, obvious and in the vicinity of-infrared
We also gauge the enhanced pulses�?temporal pulse condition and spectral transmission potential. We Ensure that our goods meet the requirements for OPCPA purposes.
A: A superior harm threshold assures the crystal can handle additional power without having degrading, leading to longer lifespan and regular efficiency.
The energy density within your beam really should be calculated with regard to J/cm2. The graph to the right demonstrates why expressing the LIDT being an Strength density gives the most effective metric for brief pulse sources. With this regime, the LIDT supplied as an Electricity density could be applied to any beam diameter; one won't must compute an adjusted LIDT to adjust for changes in spot measurement.
In addition, the structural and compositional characteristics of BBO offer it with exceptional thermal stability and resistance in opposition to environmental challenges.
Having said that, in many circumstances, the real difference in the elemental and next harmonic pulse velocities might cause 1 pulse to significantly lag one other.
Hence, the 2nd harmonic pulse spectrum, proven on the appropriate, provides a spectral width around similar to The best case. Ideally, each click here and every frequency in the elemental pulse spectrum might be concurrently phase matched.
No matter if you’re a researcher, a laser method designer, or an enthusiast, we hope this article has answered your questions on BBO crystals.
