The crystal axis is c. The Main ray is parallel to your direction used to measure the tuning angle (θ), that is optimized through phase matching. Conversion efficiency is optimized for rays parallel to the Main ray and worse for rays at larger angles (ψ) to the chief ray.

A2: Sure, prolonged exposure to humidity can degrade the optical functionality of BBO crystals. Humidity can result in water absorption within the crystal floor, that may influence its optical properties.

As a way to use the desired CW damage threshold of the optic, it is necessary to learn the following:

Nonetheless, to fully use the probable of BBO crystals, it can be critical to be aware of their Homes and how to tackle and retail store them effectively. These crystals demand watchful dealing with to avoid harm to their surfaces and will be stored within a dry, great put to take care of their optical general performance.

Finally, the huge-angle tunability of BBOs facilitates customization like never ever right before. With regards to the precise necessities of the software, the crystal can be altered with precision, guaranteeing the output is usually optimized.

Thorlabs expresses LIDT for CW lasers as being a linear power density measured in W/cm. With this routine, the LIDT presented to be a linear electricity density might be applied to any beam diameter; a single would not must compute an modified LIDT to regulate for alterations in spot sizing, as demonstrated through the graph to the right. Regular linear electrical power density may be calculated utilizing the equation beneath. 

Though the above mentioned procedure provides a great rule of thumb for LIDT values, make sure you Make contact with Tech Assistance If the wavelength differs from the required LIDT wavelength. If the ability density is a lot less than the modified LIDT on the optic, then the optic ought to function for your personal application. 

The hurt Evaluation are going to be completed on an identical optic (customer's optic will not be destroyed). Tests could end in additional expenditures or lead periods. Get in touch with Tech Support To learn more.

This property sets it apart from linear optical materials that don’t alter the frequency of sunshine passing by way of them. Such a distinguishing feature forms the muse for any myriad of purposes that BBO can serve.

Fluorescence excitation is an additional realm in which the 266nm era showcases its importance. Fluorescence involves the absorption of sunshine by a fabric and the following emission of light at another wavelength. The 266nm mild is extremely productive in interesting get more info selected fluorescent products, building them glow brightly and letting for their detection and examine.

A: The wide transparency vary features flexibility, letting BBO crystals for use across a diverse array of wavelengths and purposes.

During the huge entire world of nonlinear optical crystals, BBO crystals jump out as pioneers, especially in the realm of 266nm generation.

The 266nm technology refers back to the production of ultraviolet light-weight by using a wavelength of 266 nanometers.

And finally, spectroscopy, the examine of interactions amongst issue and electromagnetic radiation, tremendously benefits from your 266nm era. In spectroscopic programs, unique wavelengths of light interact in another way with resources, supplying a spectrum which can be analyzed to find out the material’s Qualities or composition.
