Optical parametric oscillation (OPO): We utilize OPO to determine our items�?nonlinear conversion effectiveness and period-matching angle for just a offered enter wavelength and sign/idler wavelengths. We make sure that our objects meet the requirements for OPO apps.
The choice on the most fitted crystal materials for your specified software is often considerably from trivial; it need to include the thought of many factors. As an example, a superior nonlinearity for frequency conversion of ultrashort pulses won't support In the event the conversation size is strongly minimal by a big team velocity mismatch as well as the small injury threshold limits the applicable optical intensities.
Thorlabs provides a large choice of optics optimized for use with femtosecond and picosecond laser pulses. You should see down below for more information.
It truly is greatly employed for nonlinear frequency conversion inside the ultraviolet, obvious, and around-infrared. The BBO crystal may be the most critical nonlinear crystal for in the vicinity of-infrared optical parametric chirped-pulse amplifiers, which at present supply several optical cycle pulses with large regular and ultrahigh peak powers.
Normally, the crystal materials ought to have a superior optical transparency for all wavelengths included �?as an example, for pump, signal and idler in an optical parametric amplifier.
Their exceptional Homes make them a most well-liked option for several demanding and superior-precision optical applications.
The slicing angle relies upon upon the popular phase-matching issue for frequency conversion apps. Period matching describes matching the stage speeds of various beams linked to nonlinear processes so they Create up constructively in excess of fars away In the crystal.
The length with the crystal is a crucial parameter to think about when optimizing the SHG process to the parameters of unique enter pulses. Absent stage-matching and temporal stroll-off results, the SHG output boosts exponentially with crystal length. The intention when buying an SHG crystal will be to harmony the crystal duration with the constraints determined by the fundamental pulse. Lowering the crystal thickness lessens effects relevant to both of those stage-matching bandwidth constraints and temporal stroll-off, which happen to be straight similar.
For buyer convenience the crystals can be mounted in an one" anodized aluminum (Al) mount. The mounted crystals is often even more mounted in a traditional 1" mirror mount to generally be angle tuned for section matching (as demonstrated to the ideal). Drinking water-cooled mounts for high electricity purposes is often provided on ask for.
The Vitality density of your beam ought to be calculated regarding J/cm2. The graph to the appropriate exhibits why expressing the LIDT as an Electrical power density offers the very best metric for brief pulse resources. In this routine, the LIDT provided being an Vitality density is often applied to any beam diameter; 1 will not ought to compute an altered LIDT to regulate for changes in location sizing.
At this kind of a specific wavelength, the light possesses unique Attributes that happen to be priceless to specific State-of-the-art programs. Let’s delve deeper into the necessity of this individual more info mild production.
Nonetheless, in many cases, the difference in the elemental and second harmonic pulse velocities can result in one particular pulse to drastically lag one other.
GWU-Lasertechnik has greater than thirty decades of knowledge in distributing laser crystals. Select GWU to get pleasure from our wide expertise and in-industry expertise!
Humidity can result in drinking water absorption around the crystal area, which might degrade its optical overall performance. The quality of the incident light, including its wavelength, depth, and polarization, could also have an effect on the functionality of BBO crystals in a variety of programs.
