This path will also allow compensating thermally induced depolarization and, according to the estimates, will ensure the isolation of mid-IR radiation of a kilowatt power level. The device can be compactified by using a different optical isolation scheme and a different organization of the magnetic system. The level of cold depolarization can be reduced, by annealing the magneto-optical elements. Ways to improve the device are discussed. Estimates show the possibility of isolating radiation with a power of up to 200 W with the isolation ratio of the device of ~25 dB. For studying the limitations of the isolator in terms of operating power, experiments with more powerful radiation at a wavelength of 1075 nm were performed. No thermally induced depolarization effects were observed for radiation with a wavelength of 1940 nm up to 20 W. The isolation of radiation with a wavelength of 1940 nm was demonstrated. We developed the FI for high-power mid-IR radiation based on CVD-ZnSe polycrystals and studied its characteristics. Isolators for high-power radiation with a wavelength of 1.5-2 µm are especially important for the solid-state lasers in order to cover the entire mid-IR range. and its affiliated companies under the condition that such use is limited to providing me with information regarding their products, services, and solutions relevant to my photonics needs or for their customer relations and market research activities.High-power Faraday isolators (FIs) for mid-IR radiation are of great practical importance, since they expand the capabilities of constructing optical schemes of solid state mid-IR lasers, which have progressed significantly in recent years.

Previous to his role at Excelitas, he held the position of development engineer for optical modules at AGFA-Gevaert AG in 1998 after completing his PhD in physics. These Isolator has the high damage threshold and high transmission and high isolation in customized 780-1100nm wavelength range.

He first joined the company in 2007 as product manager of optical systems and later became product manager for magneto and electro optics as well as fibers and lasers. High Power Free Space Polarization Dependent Faraday Isolator (HIO) is used for avoiding deleterious effect to Fiber Laser from the reflecting light. So in the forward direction, the rotation is positive 45°. That is, the polarization rotation due to the Faraday rotator is always in the same relative direction. Volker Melzer is Product Manager of Laser Technologies at Excelitas. Optical isolators are different from 1/4 wave plate based isolators because the Faraday rotator provides non-reciprocal rotation while maintaining linear polarization. Register below to view this webinar recording to learn more about the fundamentals of faraday isolators and the applications of low and high power isolators across the spectral range of UV to NIR. We will also highlight a few examples of designs and applications for various types of our LINOS Faraday Isolators. This webcast will discuss the basics of Faraday Isolators and cover examples of several applications of low and high power isolators across the spectral range from UV to NIR. Today, many lasers and laser applications are utilizing Faraday Isolators to enable proper operation of laser systems. A Faraday Isolator is often the best tool to avoid the instabilities and protect the laser from back reflection. A basic principle of laser operation is stimulated emission which poses a challenge with back reflection into the laser cavity potentially causing laser power to become unstable.
This effect became fundamentally important with the invention of the laser. Faraday Isolators date back to 1845 when Michael Faraday discovered the magneto-optical effect when studying the influence of a magnetic field on plane-polarized light waves.
