HiLASE experiments showed KTF as an ideal candidate for the next generation of high-average-power Faraday isolators

The HiLASE’s Numerical Modelling team, led by Dr. Slezák, jointly with the team from the National Institute for Fusion Sciences (NIFS), Gifu, Japan has successfully characterised the magneto-optical properties of a Potassium Terbium Fluoride (KTF) crystal, manufactured by Northrop Grumman Synoptics, North Carolina, USA.

KTF is a key element for high-performance optical isolators, such as Faraday isolators, which are required by many industrial and scientific laser systems to achieve efficient optical separation between the user application and the high-power laser amplifiers, and to prevent dangerous light feedback into a laser cavity.

Initial experiments showed that KTF is an ideal candidate for the next generation of high-average-power Faraday isolators. Results were published in Optics Letters (vol 45, No.7, 1 April 2020, pp. 1683-1686).

With funding support from the Technology Agency of the Czech Republic (TA ČR), HiLASE developed a high-performance functional sample of a 100W Faraday Isolator and is now looking for industrial partners interested to commercialise this high-average-power Faraday Isolator.
