Non-linear Optical (NLO) crystals give an enormously versatile Remedy for producing new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is used by a considerable and continuously increasing range of programs, from production of medical lasers, quantum networking & computing by to environmental sensing as well as numerous others.
Nonetheless, it’s important to note that whilst BBO crystals can transmit UV mild, they ought to be taken care of with care when Employed in UV purposes to forestall likely harm to the crystal and make sure protection.
Their significant damage threshold and excellent thermal security make them suited to use in large-electricity laser devices, although their wide transparency variety permits them to operate using a wide selection of laser wavelengths.
The section-matching abilities of BBO crystals ought to have special mention. While in the intricate dance of photons, wherever conversion from a person wavelength to another is often desired, the period-matching provided by BBO makes certain that Power losses are minimum.
linear absorption, which might trigger heating at significant optical electricity degrees, so which the phase matching is disturbed, and thermal lensing may well come about
The calculation higher than assumes a uniform beam intensity profile. You need to now take into consideration hotspots inside the beam or other non-uniform depth profiles and roughly calculate a highest power density.
This generate-up will describe how we create large-good quality BBO crystals at our firm. We may also evaluate some advantages and difficulties of applying BBO crystals for regularity conversion.
Nonlinear Crystals of possibly β-barium borate (BBO) or lithium triborate (LBO) are used for frequency conversion of laser sources. BBO crystals characteristic thicknesses from 0.2mm to 0.5mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The crucial and noncritical period matching LBO crystals are ideal for next or third harmonic generation of Nd:YAG and Yb:doped lasers.
Significant-precision laser microfabrication is a technique in which components are processed and modified over a microscopic scale. This method requires a laser supply that can create particularly centered and precise beams of light. The 266nm wavelength is very appropriate for this on account of its small wavelength, which makes certain that the laser beam is often concentrated to an exceedingly compact place size.
Other phase matching problems will also be possible. Essential Form-II phase matching works by using an oe-o or eo-e for positive and adverse uniaxial crystals. Non-essential section matching makes use of crystal temperature to obtain stage matching rather than angular tuning.
Pumped from the fourth harmonic of a Nd:YAG laser (at 266nm), a tunable OPO with signal wavelength assortment concerning 422nm and 477nm has long been noticed by angle-tuning a type I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields in excess of 50µJ (optimum a hundred thirtyµJ),
The production of Beta-Barium Borate (BBO) crystals is a posh and meticulous approach that requires a higher volume of precision and abilities. This process, referred to as the flux approach, begins Along with the preparation of a mix of barium read more borate and barium fluoride.

Since the refractive index would not change linearly with frequency in dispersive crystals like β-BBO, it truly is impossible to optimally stage match each individual frequency inside the enter pulse's spectral vary Using the corresponding 2nd harmonic frequency while in the created pulse.
