They can be employed for frequency doubling invisible one particular-micron mild into 532nm seen green gentle, an application that has previously belonged to KTP crystals.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a relatively solid nonlinearity. They tend to be used for nonlinear frequency conversion and likewise for electro-optic modulators. Both equally elements can be found in congruent and in stoichiometric sort, with crucial discrepancies relating to periodic poling and photorefractive outcomes (see down below). Lithium niobate and tantalate will be the most often employed resources from the context of periodic poling; the ensuing materials are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.
Critical Terms: Nonlinear Crystals , SHG crystal , SFG crystal , LBO Crystal Lithium Triborate (LiB3O5 or LBO) is often a type of nonlinear crystal that is commonly Utilized in the era of significant-power laser radiation. It has a higher injury threshold plus a wide transparency range between the ultraviolet on the in close proximity to-infrared area, making it suited to many different laser purposes.
Owning the crystal Slash for NCPM and holding the crystal at distinct temperature, the walkoff angle is sort of zero, therefore it makes it possible for to have a extremely prolonged crystal and achieve excellent conversion effectiveness. The LBO crystal is generally utilized to generate second and third harmonics of neudymium based mostly lasers like Nd:YAG, Nd:YVO4. One more important software of the LBO crystal is frequency conversion in optical parametric oscillators (OPO).
linear absorption, which often can bring about heating at high optical energy degrees, so which the phase matching is disturbed, and thermal lensing may possibly take place
The most typical utilization of LBO is In brief pulse, superior pulse price lasers; the upper electricity density the better. It is usually really well suited for non-significant period matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at ninety% conversion performance with no wander-off.
Optical microscopy can be used to discover surface area defects, like scratches, cracks, and LBO Crystal pits, that can impact the general performance of your crystal in many applications. Optical microscopy can also be made use of to determine the crystal thickness and uniformity.
GWU-Lasertechnik offers all common nonlinear crystals like LBO, BBO and KTP with a broad assortment of technical specs. Beside the properly-recognized components, revolutionary crystals like CLBO or BiBO with fantastic Attributes for e. g. deep-UV technology or high-electrical power ultrashort pulse lasers are available. Irrespective of if unique parts for R & D uses are demanded or Price tag-productive quantities in tiny, medium or big batches with in-time shipping and delivery with the production line are necessary: GWU’s devoted provider helps you to locate the best Main elements for the software.
This cautiously curated temperature profile makes certain that the mixture solidifies inside a uniform method, forming an individual crystal structure. A critical facet of the Flux approach will be the temperature gradient, that has an important impact on the scale and high-quality in the crystal. Making sure a secure temperature gradient is vital for acquiring massive, significant-top quality LBO Crystals.
Diode pumped stable state lasers with frequency converting LBO are hugely reputable, compact, and use less energy than the normal lasers they usually switch. In many situations there was no acceptable or inexpensive laser to complete the features that DPSS lasers have enabled.
LBO is stage matchable with the SHG and THG of Nd:YAG and Nd:YLF lasers, using both sort I or kind II interaction. For that SHG at space temperature, type I section matching could be attained and has the maximum powerful SHG coefficient while in the principal XY and XZ planes in a broad wavelength vary from 551 nm to about 3000 nm.
Human tissue absorbs distinctive wavelengths selectively, according to the form, though transmitting other wavelengths. Ideally a wavelength is selected to penetrate bodily fluids typically, still be absorbed strongly via the concentrate on with out damaging encompassing tissue.
LBO is a non-linear crystal. The significance of that is it can alter the wavelength of the enter beam to a distinct wavelength output. GAMDAN LBO has primarily no absorption above an array of wavelengths, from 160 to 2600 nanometers. Which suggests it is a wonderful choice for frequency tripling the emission of well-known a person-micron lasers into your UV, at all over 355 nanometers.
Crystal growth can be a essential move within the production of substantial-high quality LBO nonlinear crystals. The selection of crystal advancement procedure can substantially impact the crystal top quality and optical properties of the ensuing crystal. The Czochralski, flux, and TSSG procedures tend to be the most commonly made use of approaches for your creation of LBO nonlinear crystals, Every single with its benefits and drawbacks.
