Fiber to Free Space 500W 1064nm Isolator

Fiber to Free Space 1064nm Isolator (500W)

A Fiber to Free Space 1064nm Isolator (500W) is a device used in high power laser systems that transmit light at a wavelength of 1064 nanometers (nm) and can handle up to 500 watts of average laser power. They are important for protecting the laser source from reflected light, which can damage the laser or cause it to operate erratically.

Fiber optic isolators work based on the magneto-optic effect, where light traveling in one direction experiences a different phase shift than light traveling in the opposite direction through a material in a magnetic field. This phase shift allows the isolator to transmit light in the forward direction while blocking light traveling in the reverse direction.
