LBO is a superb NLO crystal for OPOs and OPAs that has a broadly tunable wavelength selection and superior powers. The unique properties of form I and kind II period matching and also the NCPM depart an enormous place from the exploration and apps of LBO's OPO and OPA.
LBO crystals with one particular end or the two finishes Reduce for the Brewster angle and uncoated are offered. Such crystals are sometimes used to minimize the floor decline with out reduction with the problems threshold by an AR coating for prime power apps.
But LBO has greater transparency, less flaws, and won't are afflicted by grey tracking. The end result is better electricity and life span ability. Additionally it is cheaper than hydrothermal KTP, so it's begun to switch KTP in the more demanding apps.
Observe that even when the nominal depth is down below the nominal problems threshold, there may be problems on account of fluctuations inside the beam ability or regional depth (e.g., if a beam profile has “sizzling spots�?, or resulting from isolated defects in a crystal, which happen to be a lot more delicate as opposed to frequent crystal content.
linear absorption, which can result in heating at higher optical energy ranges, so the period matching is disturbed, and thermal lensing could take place
The optimal crystal orientation for maximum SHG performance in LBO nonlinear crystals is the kind I stage-matching direction, which corresponds to your 90-diploma angle amongst the input and output polarizations.
It will involve employing a seed crystal to initiate crystal development from a supersaturated Remedy. The TSSG method can make crystals with managed defect density and orientation, that's important for reaching exceptional stage-matching conditions.
UV lasers excel at marking. Elements that are usually transparent, together with widespread glass, lenses, and prisms, numerous kinds of plastics and organic and inorganic components is usually precisely marked with frequency tripled light-weight.
The significant damage threshold is particularly critical in several optical purposes as it may cope with superior power lasers with out deteriorating or triggering product failure.
Probably the most popular programs of LBO nonlinear crystals is frequency doubling, wherever the elemental frequency of the laser beam is doubled to produce a higher frequency output.
In spectroscopy, OPA is utilized to crank out tunable gentle sources for click here various purposes, for example chemical Evaluation and material characterization. In telecommunications, OPA is utilized to amplify and convert alerts in optical conversation methods.
The Czochralski strategy permits the creation of large LBO crystals with outstanding crystal excellent and very low defect density. However, the method is relatively slow and needs watchful control of the temperature, rotation, and pulling fee to keep up uniform expansion.
The selection of approach depends upon the precise Homes that need to be characterised, like crystal composition, defects, and optical Homes.
By examining the emitted gentle, the luminescent properties and defects of your crystal might be determined.
