![]() 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. These Isolator has the high damage threshold and high transmission and high isolation in customized 780-1100nm wavelength range. 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.

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. ![]() We developed the FI for high-power mid-IR radiation based on CVD-ZnSe polycrystals and studied its characteristics. The isolation of radiation with a wavelength of 1940 nm was demonstrated. No thermally induced depolarization effects were observed for radiation with a wavelength of 1940 nm up to 20 W. 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. 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. Ways to improve the device are discussed. The level of cold depolarization can be reduced, by annealing the magneto-optical elements. The device can be compactified by using a different optical isolation scheme and a different organization of the magnetic system. 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.
