Optical parametric oscillation (OPO): We utilize OPO to determine our goods�?nonlinear conversion performance and period-matching angle for the supplied input wavelength and signal/idler wavelengths. We make sure that our items satisfy the requirements for OPO applications.
Common cleaning of BBO crystals can be recommended to maintain their optical efficiency. This may be carried out using a gentle cloth or lens tissue moistened having a delicate solvent, which include isopropyl Liquor.
Thorlabs provides a large choice of optics optimized for use with femtosecond and picosecond laser pulses. Remember to see underneath for more information.
While in the wide earth of nonlinear optical crystals, BBO crystals stand out as pioneers, especially in the realm of 266nm technology.
Hygroscopic crystal supplies deteriorate when they are not always saved in sufficiently dry air (or simply a dry purge gasoline). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It could be valuable to maintain this kind of crystal in a to some degree elevated temperature, that makes it easier to keep it dry.
The group velocity is definitely the speed of the heart beat, or even more formally the envelope of the electric subject. The team index likewise governs the speed on the envelope relative into the speed of sunshine inside of a vacuum and it is get more info dependent on the dispersion of the fabric.
The Rayleigh variety quantifies the space, measured through the beam waistline, more than which the beam diameter is approximately continual. The shorter the Rayleigh range, the bigger the speed of divergence.
When 1 of these β-BBO Crystals is mounted during the RSP1 mount, the crystal will probably be centered above the 8-32 (M4) hole during the mount's base with no need for spacers.
Beam diameter is usually crucial to know when evaluating destruction thresholds. Whilst the LIDT, when expressed in units of J/cm², scales independently of location dimension; huge beam measurements are more likely to illuminate a larger amount of defects which can result in better variances while in the LIDT [four].
To avoid this, BBO crystals needs to be stored in the dry natural environment and appropriately sealed when not in use. Furthermore, any cleaning system must be followed by thorough drying to eliminate any residual moisture.
The 4 lessen figures illustrate the team velocity delay (temporal stroll-off) improves as the pulses propagate by means of the fabric. The temporal wander-off is illustrated for distances Z0 through Z3, that are indicated over the diagram at best.
BBO nonlinear crystal is a destructive uniaxial crystal. It provides phase matching for a variety of second-get interactions Practically over its overall transparency range. This transparency ranges from 185 nm to three.3 µm, as inferred from transmittance measurements applying crystal samples of a few mm thickness.
Within the complex tapestry of photonics, the 266nm technology, backed through the prowess of BBO, emerges as being a thread of paramount importance.
The size of your SHG crystal substantially has an effect on the spectral width from the reference pulse, or alternatively the bandwidth with the SHG filter.
