A Simple Key For BBO Crystal Unveiled

Blog Article

Both equally broad-bandwidth pulses and temporal walk-off trigger a discount from the conversion effectiveness, and worsen the optical high quality of the next harmonic pulses. The appropriate crystal thickness need to be chosen to attenuate both of those consequences.

Hi, thanks for speaking to Thorlabs. The wavelength ranges with the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations may be produced by reaching out to us at techsupport@thorlabs.com

five mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical period matching LBO crystals are ideal for next or third harmonic technology of Nd:YAG and Yb:doped lasers.

Crystal life span may also be strongly depending on the fabric high quality, While selected degradation phenomena seem like intrinsic limits of the fabric.

Artifex Engineering provides finished crystal optics for non-linear applications. Check out our product or service page To find out more. We sit up for your inquiry.

BBO crystals have two refractive indices: ne for incredible rays and no for standard rays. The distinction between ne and no depends upon the wavelength of light and the crystal’s temperature.

When laser light-weight is focused to some location, the diameter in the beam midsection would be the focal location sizing, and the speed at which the light diverges with the beam waistline is related to the Rayleigh assortment (zR).

Nonlinear Crystals of both β-barium borate (BBO) or lithium triborate (LBO) are employed for frequency conversion of laser sources. BBO crystals characteristic thicknesses from 0.2mm to 0.5mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The important and noncritical stage matching LBO crystals are ideal for next or 3rd harmonic era of Nd:YAG and Yb:doped lasers.

It’s vital that you stay away from employing abrasive components or powerful solvents, as these can scratch or otherwise problems the crystal’s floor. Frequent cleaning may help sustain the crystal’s optical general performance and extend its lifespan.

A3: Indeed, BBO crystals have a wide transparency array that extends in to the ultraviolet spectrum. This makes them suited to applications that require ultraviolet light-weight, including UV spectroscopy and UV laser devices.

No matter if it’s in the event of far more effective lasers, the exploration of quantum phenomena, or the generation of new optical products, BBO crystals will definitely continue to Enjoy a pivotal purpose.

Pulsed lasers with large pulse repetition frequencies (PRF) may perhaps behave similarly to CW beams. However, this is very depending on aspects for example absorption and thermal diffusivity, so there isn't any reputable strategy for identifying every time a superior PRF laser will harm an optic as a result of thermal outcomes.

As a result, the 2nd harmonic pulse spectrum, proven on the ideal, incorporates a spectral width approximately the same as The best situation. Ideally, every frequency in the basic pulse spectrum would be concurrently section matched.

Large angular wander-off BBO crystals have a huge angular stroll-off that triggers spatial splitting among numerous polarization sections of sunshine when circulating having a more info BBO crystal.
