BBO Crystal - An Overview

BBO Crystal - An Overview

Blog Article

Optical crystals can exhibit different styles of optical nonlinearities, which can be used in several methods:

This good-tuning capacity signifies that BBO crystals can cater to each generic and hugely specialised requires with equal finesse.

Thorlabs provides a good selection of optics optimized for use with femtosecond and picosecond laser pulses. Remember to see under To learn more.

The SHG gentle is polarized within the XZ aircraft and is orthogonal to the two the Eo plus the k-vector. As an alternative to decompose the polarization in the SHG gentle into Ex and Ez elements, the electric field is usually called an extraordinary wave (E'e). The refractive index for this amazing wave, n'e, improvements to be a purpose of θ. n'e(θ) is usually calculated using the equation in Determine thirteen. The ellipse defining the remarkable index of refraction as being a purpose of θ is really a conic part of the index ellipsoid.

BBO crystals is usually cleaned utilizing a comfortable cloth or air blower. For stubborn stains, a delicate detergent or isopropyl alcohol can be employed. It’s essential to steer clear of working with abrasive supplies that could scratch the crystal’s surface area. When cleansing BBO crystals, it’s essential to use a gentle, circular movement to stay away from scratching the surface area.

Normal cleansing and appropriate storage will help prolong the lifespan of BBO crystals. It’s also imperative that you avoid exposing the crystals to problems outside their specified running range, as this could potentially cause long-lasting problems.

Many of the typical nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation are offered from inventory. Buyer-certain dimensions and AR coatings are made available at competitive rates.

the chemical longevity; e.g., some crystal resources are hygroscopic, Many others undergo chemical improvements when heated inside of a vacuum chamber for software of a dielectric coating

Beam diameter is also crucial that you know when comparing injury thresholds. Even though the LIDT, when expressed in models of J/cm², scales independently of location dimension; substantial beam measurements are more likely to illuminate a larger amount of defects which can lead to greater variances while in the LIDT [4].

While this general guideline presents a general development, It is far from a quantitative Assessment of LIDT vs wavelength. In CW purposes, For illustration, destruction scales a lot more strongly with absorption within the coating and substrate, which won't always scale properly with wavelength.

These crystals are distinctive due to their power to change the frequency of light passing by means of them, a property that is very wanted in various fields such as laser technology and quantum physics. The flexibility of BBO crystals can make them a crucial element in lots read more of Sophisticated optical units.

The spectrally narrowed SHG pulse spectrum is said being apodized, considering that an impact of the elemental pulse exceeding the maximum input bandwidth Restrict would be the elimination of the very best and cheapest frequencies from the SHG pulse spectrum.

Any contamination can degrade the optical overall performance in the crystal and possibly result in problems less than higher laser electrical power. When storing BBO crystals, they ought to be positioned in a very protecting circumstance to prevent physical destruction and dust accumulation.

Our crystals are Utilized in a wide range of apps, like numerous kinds of nonlinear frequency conversion and electro-optics, and also quantum technological innovation.
