Non-linear Optical (NLO) crystals deliver an enormously flexible Resolution for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a sizable and continually growing variety of apps, from production of health-related lasers, quantum networking & computing via to environmental sensing together with lots of Many others.
Even though the above mentioned procedure presents a very good guideline for LIDT values, be sure to Get in touch with Tech Support When your wavelength differs from the required LIDT wavelength. If your energy density is a lot less than the altered LIDT on the optic, then the optic really should do the job for your application.
A1: Of course, BBO crystals Have a very large harm threshold, generating them well suited for substantial-ability laser units. Their capacity to withstand higher laser intensities without having suffering from optical problems can make them a wonderful choice for frequency conversion in large-electric power lasers.
Inside the broad earth of nonlinear optical crystals, BBO crystals jump out as pioneers, particularly in the realm of 266nm generation.
Rather than the reference pulse electrical power spectrum comprising an apodization filter, inside the spatial area the filter would be in NA. The angular domain apodization filter nonetheless, is simply in a single-dimension outlined from the airplane k and .
Typical cleansing and good storage will help lengthen the lifespan of BBO crystals. It’s also imperative that you steer clear of exposing the crystals to ailments exterior their specified functioning range, as this may cause everlasting destruction.
The section velocity is the rate at which the field copyright, i.e. the sine wave, travels in a fabric. The rate at which a pulse envelope travels in a material is called the team velocity and defines the pace from the Power packet comprising the optical pulse touring by the fabric.
A second issue would be that the team velocity mismatch in between the 2nd harmonic and essential-frequency pulses will bring about just one pulse lagging the opposite as the two propagate. This is named temporal wander-off and can occur even less than ideal phase-matched ailments.
Every aspect of BBO, from its get more info atomic structure to its broad software spectrum, underscores its pivotal part in present day science and technologies.
A: The broad transparency array presents flexibility, allowing for BBO crystals for use across a various variety of wavelengths and applications.
Pumped through the fourth harmonic of the Nd:YAG laser (at 266nm), a tunable OPO with signal wavelength array among 422nm and 477nm has been noticed by angle-tuning a sort I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields in excess of 50µJ (maximum 130µJ),
In addition, BBO crystals are known for their large nonlinear coefficient, which permits them to efficiently change the frequency of sunshine.
Third harmonic generation (THG): We use THG to measure our items�?nonlinear conversion performance and stage-matching angle for any offered input wavelength. We Be certain that our solutions satisfy the specs for THG applications.
The size in the SHG crystal significantly impacts the spectral width from the reference pulse, or alternatively the bandwidth of the SHG filter.
