Optical parametric oscillation (OPO): We utilize OPO to find out our things�?nonlinear conversion efficiency and section-matching angle for any provided enter wavelength and sign/idler wavelengths. We make certain that our objects fulfill the requirements for OPO applications.
Howdy, thank you for getting in contact with Thorlabs. The wavelength ranges of your antireflective coatings on these β-BBO crystals align With all the respective wavelength bands that these crystals are optimized for.

This is particularly critical in biological and clinical investigate wherever specific compounds or cells are tagged with fluorescent markers. The 266nm gentle can excite these markers, generating them stand out Plainly versus a qualifications, thereby facilitating detailed analysis.
The Z-axis is parallel into the optical axis of your crystal along with is additionally known as the wonderful axis. The X- and Y-axes are parallel towards the optical axis and are referred to as normal axes.
The 2nd harmonic gentle is then polarized parallel for the aircraft. Angle tuning adjusts θ and is particularly done by rotating the crystal within the Y-axis.
The calculation previously mentioned assumes a uniform beam depth profile. You must now take into consideration hotspots during the beam or other non-uniform intensity profiles and approximately estimate a optimum electrical power density.
Determine 22: The diagram at the best shows two pulses with different Centre frequencies incident on a fabric. The team velocity hold off concerning the pulses if they enter the fabric is zero.
We also gauge the enhanced pulses�?temporal pulse form and spectral transmission capability. We Be sure that our merchandise meet up with the necessities for OPCPA programs.
Physically, when the basic spectrum is effectively inside the reference pulse spectrum, the SHG pulse depth profile may be the sq. of the basic intensity profile, properly truncating the length. This circumstance is illustrated in Figure 20.
BBO crystals may also be Employed in electro-optic modulation, a way used to control the stage, polarization, or amplitude of a read more light-weight beam. Moreover, they come across use in optical parametric oscillation, a procedure that generates two output waves from one particular enter wave, and quantum optics, a subject that explores the quantum interactions of sunshine and matter.
The effectiveness with the SHG process decreases substantially as the fundamental beam diverges from its target, For the reason that pulse Electricity is distributed across a larger beam cross segment.
Also, BBO crystals may also be recognized for their large nonlinear coefficient, which permits them to effectively transform the frequency of light.
This can be the so-termed oo-e arrangement, as the two photons from the fundamental are polarization-oriented alongside the ordinary axis and the next harmonic photon's polarization is in the remarkable airplane.
Whether or not the crystal substance or coating isn't sensitive to water, little water droplets could emphasis laser radiation a lot more tightly than underneath usual Procedure, and therefore hurt the crystal content.
