Optical crystals can exhibit distinct kinds of optical nonlinearities, which may be utilized in various means:
Although the above treatment gives a very good guideline for LIDT values, make sure you Make contact with Tech Guidance In case your wavelength is different from the required LIDT wavelength. When your electricity density is lower than the modified LIDT on the optic, then the optic really should perform for your personal software.
five mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are ideal for second or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
So as to use the specified CW destruction threshold of an optic, it is necessary to be aware of the subsequent:
Artifex Engineering provides finished crystal optics for non-linear apps. Take a look at our products website page for more information. We sit up for your inquiry.
Quite a few factors can have an impact on the efficiency of BBO crystals. These involve temperature, humidity, and the quality of the incident mild. Suitable handling and storage will help preserve the crystal’s efficiency. Temperature can have an effect on the stage-matching situations of BBO crystals, which subsequently impacts their efficiency in frequency conversion applications.
Please Observe that we have a buffer designed in between the desired damage thresholds on the internet and the checks which We have now accomplished, which accommodates variation between batches. Upon request, we can provide unique test information and facts and also a tests certification.
The duration in the crystal is a vital parameter to consider when optimizing the SHG procedure for that parameters of certain input pulses. Absent section-matching and temporal more info stroll-off effects, the SHG output will increase exponentially with crystal length. The intention when choosing an SHG crystal is always to stability the crystal length with the restrictions based on the basic pulse. Decreasing the crystal thickness lowers results related to the two phase-matching bandwidth constraints and temporal walk-off, which might be immediately linked.
Higher-precision laser microfabrication is a way in which components are processed and modified over a microscopic scale. This method needs a laser source that can make incredibly concentrated and exact beams of sunshine. The 266nm wavelength is particularly suitable for this resulting from its quick wavelength, which makes certain that the laser beam can be concentrated to an incredibly tiny location dimensions.
GWU-Lasertechnik offers all common nonlinear crystals like LBO, BBO and KTP having a wide a number of technical specs. Beside the properly-recognized elements, progressive crystals like CLBO or BiBO with excellent Attributes for e. g. deep-UV era or superior-energy ultrashort pulse lasers can be obtained. Despite if person pieces for R & D functions are expected or Price-effective quantities in tiny, medium or large batches with in-time shipping for the manufacturing line are necessary: GWU’s committed assistance helps to discover the finest Main components for the application.
NCPM occurs when the input beam propagates at an angle apart from zero or 90 degrees worrying one of the significant axes, including the Z-axis. Its polarization is parallel to that axis, such as Z-polarized.
The crystal axis is c. The chief ray is parallel to the route accustomed to evaluate the tuning angle (θ), which can be optimized in the course of period matching. Conversion effectiveness is optimized for rays parallel into the chief ray and worse for rays at greater angles (ψ) for the chief ray.
From the health care area, imaging stands out as on the list of vital processes, performing being a window into the human entire body. The precision and clarity supplied by the 266nm era have revolutionized sure imaging methods. This certain wavelength, when utilized in imaging, can make sharp, significant-resolution illustrations or photos that assist clinicians in determining minute abnormalities or alterations in tissue constructions that might otherwise be overlooked.
A further Similarly intriguing application is optical parametric oscillation. In this, BBO permits the conversion of a photon into two photons with different frequencies, the sum of which equals the first photon’s frequency.
