5 Simple Techniques For BBO Crystal

Optical parametric oscillation (OPO): We make the most of OPO to determine our items�?nonlinear conversion overall performance and section-matching angle for your supplied enter wavelength and sign/idler wavelengths. We make sure that our merchandise satisfy the requirements for OPO apps.
With right care and maintenance, BBO crystals can final for a few years. Typical cleaning and right storage will help extend the lifespan on the crystals. Furthermore, utilizing the crystals inside of their specified running parameters may aid stop untimely degradation.
Regrettably, it may be very hard to check the LIDT specification of the optic for your laser. You will find multiple regimes in which a pulsed laser can destruction an optic which is predicated within the laser's pulse duration. The highlighted columns within the table under define the related pulse lengths for our specified LIDT values.
Now Review the most Electrical power density to that which happens to be specified since the LIDT for the optic. Should the optic was analyzed in a wavelength other than your functioning wavelength, the hurt threshold have to be scaled appropriately [3].
Even very well under the edge for instant harm, some crystal products exhibit a constant degradation in the applied quantity, e.
The team velocity may be the pace of the heartbeat, or maybe more formally the envelope of the electric discipline. The group index equally governs the velocity of your envelope relative to your speed of sunshine inside of a vacuum and it is dependent on the dispersion of the material.
The Rayleigh selection quantifies the space, measured within the beam waist, more than which the beam diameter is approximately continuous. The shorter the Rayleigh selection, the larger sized the speed of divergence.
BBO crystals are utilized within a big range of apps because of their Remarkable optical Homes. They are generally used in laser programs for frequency conversion, which includes 2nd, 3rd, and fourth harmonic generation. This allows for your production of laser mild at different wavelengths from only one input wavelength.
Bodily, when the fundamental spectrum is properly throughout the reference pulse spectrum, the SHG pulse intensity profile would be the square of the fundamental depth profile, efficiently truncating the length. This situation is illustrated in Figure 20.
Because the dynamics of this process are remarkably issue to experimental parameters, it really is tricky to arbitrarily predict the specific outcomes on the 2nd harmonic pulse. These consequences can contain back conversion, during which second harmonic mild is converted back to fundamental light-weight, and spectral narrowing on the SHG pulse.
This assets sets it aside from linear optical resources that don’t alter the frequency of light passing by them. This kind of distinguishing function types the inspiration for just a plethora of programs that BBO can provide.
rystal surface area is horizontal and a bit over your fingers. Have a contemporary, clean up sheet of lens tissue and place it on the crystal. Make sure the lens tissue may be drawn across the crystal area. Future, place a little fall of pure isopropyl alcohol (IPA) about the lens tissue along with the crystal surface.
GWU-Lasertechnik has a lot more than 30 many years of encounter in distributing laser crystals. Choose GWU to take advantage of our broad awareness As well as in-area encounter!
The get more info 266nm wavelength provides precise interactions that other wavelengths can’t, rendering it indispensable for detecting and finding out sure compounds.
