BBO Crystal - An Overview

BBO Crystal - An Overview

Blog Article

This home is significant in lots of optical methods, because it permits the manipulation and Charge of light in ways that will not be achievable with linear optical products.

BBO is the sole NLO product which can be applied to supply the fifth harmonic technology (5HG) of Nd:YAG lasers at 213 nm. On account of a little acceptance angle and enormous angular walkoff, very good laser beam high-quality (little divergence, great mode issue, etcetera.

If the Rayleigh range is less than the crystal thickness, the gap in excess of which the beam is optimally intensive is a lot less than the crystal thickness.

Thorlabs expresses LIDT for CW lasers to be a linear electric power density measured in W/cm. During this regime, the LIDT given for a linear electric power density is often applied to any beam diameter; 1 doesn't should compute an altered LIDT to regulate for alterations in spot dimension, as shown via the graph to the appropriate. Typical linear ability density is often calculated using the equation under. 

linear absorption, which could bring about heating at substantial optical ability degrees, so that the period matching is disturbed, and thermal lensing may arise

EKSMA Optics uses cookies to supply you with the ideal shopping knowledge. In the event you proceed to employ our providers, We'll suppose that you conform to using this sort of cookies.

Now Evaluate the maximum electricity density to that that is specified since the LIDT with the optic. When the optic was tested in a wavelength besides your functioning wavelength, the hurt threshold need to be scaled properly.

BBO crystals are a significant part in several optical applications due to their Fantastic Homes. Knowledge their production, properties, dealing with, and use can website assist end users improve their efficiency and lifespan.

A5: Yes, BBO crystals have exceptional thermal security and will sustain their Houses at room temperature. Which means they are often Utilized in a variety of environments with out requiring Particular temperature Manage.

Although this general guideline provides a common craze, It's not necessarily a quantitative analysis of LIDT vs wavelength. In CW applications, For example, destruction scales extra strongly with absorption from the coating and substrate, which isn't going to necessarily scale effectively with wavelength.

At this sort of a certain wavelength, the light possesses special Qualities which can be invaluable to sure Highly developed purposes. Permit’s delve further into the significance of this specific light-weight generation.

What's more, BBO crystals may also be noted for their high nonlinear coefficient, which allows them to successfully change the frequency of light.

Within the healthcare subject, imaging stands out as on the list of vital processes, acting like a window in the human overall body. The precision and clarity furnished by the 266nm technology have revolutionized certain imaging processes. This precise wavelength, when utilized in imaging, can create sharp, significant-resolution illustrations or photos that assist clinicians in figuring out minute abnormalities or modifications in tissue buildings Which may usually be ignored.

As a result of its excellent Attributes BBO crystal has a selection of advantages for different purposes, like NOPA with fsec pulses, harmonics technology (as many as fifth) of Nd:YAG and Nd:YLF lasers, frequency doubling or tripling of femtosecond Ti:Sapphire and dye lasers, OPO at Form one and Type two stage-matching, E/O switching for Pockels cells and many other.
