What would make LBO Distinctive is its blend of a broad transparency assortment, extending from the ultraviolet on the far infrared, and an extremely substantial damage threshold.
Pulsed good condition UV lasers are investigated for making the ultrashort wavelength deep ultraviolet gentle that currently arises from excimer lasers, as used in photolithography of semiconductor chips.
Hygroscopic crystal resources deteriorate when they're not generally saved in sufficiently dry air (or simply a dry purge gas). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It can be valuable to help keep this type of crystal in a considerably elevated temperature, that makes it much easier to hold it dry.
Possessing the crystal Minimize for NCPM and maintaining the crystal at particular temperature, the walkoff angle is sort of zero, consequently it allows to have a extremely extended crystal and reach exceptional conversion effectiveness. The LBO crystal is mostly accustomed to deliver 2nd and third harmonics of neudymium dependent lasers like Nd:YAG, Nd:YVO4. Another important application with the LBO crystal is frequency conversion in optical parametric oscillators (OPO).
One of the most crucial Attributes of LBO nonlinear crystals is their capability to realize section-matching for efficient frequency conversion. Period-matching will be the issue exactly where the wave vectors of the fundamental and harmonic waves match, enabling the conversion of the elemental frequency in to the harmonic frequency.
LBO crystal (lithium triborate) is The most applied nonlinear crystal for harmonics era for short and extended pulse applications. On account of it’s somewhat smaller walkoff angle extensive crystals could possibly be utilised what lets to accomplish large conversion efficiency.
The knowing and optimization of LBO nonlinear crystals are important for the development and optimization of varied nonlinear optical equipment and purposes.
GWU-Lasertechnik gives all normal nonlinear crystals like LBO, BBO and KTP using a broad variety of specifications. Beside the well-founded website elements, modern crystals like CLBO or BiBO with outstanding Attributes for e. g. deep-UV era or higher-ability ultrashort pulse lasers can be obtained. Irrespective of if particular person pieces for R & D applications are necessary or Price tag-productive quantities in modest, medium or big batches with in-time shipping for the creation line are desired: GWU’s dedicated services really helps to discover the greatest Main parts for your application.
Applying our promoting deal, you are able to Exhibit your logo, more under your product or service description, and these will been seen by numerous photonics experts.
Nonlinear Crystals of both β-barium borate (BBO) or lithium triborate (LBO) are utilized for frequency conversion of laser resources. BBO crystals feature thicknesses from 0.2mm to 0.5mm to reduce team velocity mismatch and are perfect for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The crucial and noncritical phase matching LBO crystals are ideal for 2nd or 3rd harmonic era of Nd:YAG and Yb:doped lasers.
XRD can be employed to establish the crystal construction and orientation of LBO nonlinear crystals, that is important for obtaining optimum phase-matching ailments in a variety of applications.
Many various Attributes of a nonlinear crystal can be critical for an software e.g. in nonlinear frequency conversion:
Optical crystals can exhibit unique types of optical nonlinearities, which may be used in numerous methods:
By examining the emitted gentle, the luminescent properties and defects with the crystal can be established.
