Free Space Isolator

The free space isolator is composed of a birefringent crystal (or polarizer), a Faraday rotator and a half-wave plate. It is used in fiber lasers and can effectively stop back reflections.

Product introduction

Description:

Free-space isolators can be categorized into polarization-dependent and polarization-independent isolators.As critical components in fiber lasers,they are primarily composed of a polarizing beam splitter and a Faraday rotator.These isolators are typically used to prevent the effects of back-reflected noise or interference on the light source or optical system,effectively maintaining the stability of the optical system.
