The indispensability of LBO Crystals in these procedures has don't just spurred the evolution of laser technological innovation, but will also revolutionized its applicability, generating lasers a common feature in numerous aspects of our daily life.
You have to look at the wavelength and energy within your laser resource and decide on a crystal that is definitely transparent on the offered wavelength and might withstand the laser electrical power. And lastly, other elements like the thermal security, optical homogeneity, and nonlinear optical coefficient in the crystal also must be deemed.
We provide precision oven and temperature controller to maintain LBO crystals at a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals could be pre-set up into the oven free of charge within our manufacturing facility to your usefulness.
Last but not minimum, superior optical homogeneity guarantees uniform light-weight propagation from the crystal, causing far better beam high-quality and less distortions.
The wonderful optical homogeneity and lack of inclusions in GAMDAN substance imply fantastic undistorted wavefront output from the gadget. LBO has a very substantial inner hurt threshold due to its low absorption. That residence also avoids beam distortion from thermal expansion.
Optical parametric oscillation (OPO) is usually a nonlinear system that entails the conversion of a superior-Electrical power photon into two decreased-Vitality photons inside of a resonant cavity. LBO nonlinear crystals Have got a higher nonlinear coefficient, which makes them perfect for productive OPO.
It will involve employing a seed crystal to initiate crystal expansion from the supersaturated Option. The TSSG system can deliver crystals with controlled defect density and orientation, which is essential for acquiring optimum stage-matching conditions.
GWU-Lasertechnik offers all standard nonlinear crystals like LBO, BBO and KTP using a wide selection of specifications. Beside the nicely-proven materials, innovative crystals like CLBO or BiBO with exceptional Homes for e. g. deep-UV generation or significant-power ultrashort pulse lasers are offered. Irrespective of if particular person pieces for R & D applications are essential or Price tag-successful numbers in compact, medium or massive batches with in-time supply for that manufacturing line are essential: GWU’s dedicated company helps you to locate the finest core parts to your software.
Form II NCPM OPO pumped by a XeCl excimer laser at 308nm has realized 16.five% conversion efficiency, and moderate tunable wavelength ranges is usually acquired with different pumping resources and temperature tuning.
Nonlinear Crystals of possibly β-barium borate (BBO) or lithium triborate (LBO) are utilized for frequency conversion of laser resources. BBO crystals element thicknesses from 0.2mm to 0.5mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The essential and noncritical phase matching LBO crystals are perfect for next or third harmonic technology of Nd:YAG and Yb:doped lasers.
LBO is section matchable for the SHG and THG of Nd:YAG and Nd:YLF lasers, employing either form I or variety II interaction. For the SHG at room temperature, style I period matching is usually achieved and has the maximum efficient SHG coefficient in the principal click here XY and XZ planes in a broad wavelength vary from 551 nm to about 3000 nm.
The Czochralski strategy permits the production of large LBO crystals with great crystal top quality and low defect density. On the other hand, the method is comparatively gradual and needs very careful control of the temperature, rotation, and pulling fee to maintain uniform progress.
On top of that, LBO Crystals have made sizeable contributions into the realm of optical parametric oscillation, a system crucial for creating tunable light resources. Below, they serve as a System for that incident mild to produce two new light-weight beams, Each individual carrying diverse frequencies.
They exhibit excellent homogeneity in excess of substantial volumes and also have a significant problems threshold, but are hygroscopic and also have a lower nonlinearity.
