EOT's 250 W Dual-stage Fiber Laser Output Isolator has been specifically designed to enable safe operation of CW and pulsed fiber lasers at unprecedented average and peak power levels as well as market-leading pulse energies.
Dual-stage isolation provides industrial performance while ensuring reflected light does not promote self-lasing of amplifiers or become amplified to levels which degrade mid-stage isolators. Peak isolation at design wavelength ensures sufficient isolation over full Ramn-shifted range.
Utilizing high damage threshold and ultra-low absorbing materials, these isolators provide high transmission of light in the forward direction and strong attenuation of light in the reverse direction.

Product specifications are subject to change. All products are RoHS compliant.
a Standard fiber length is 3 m, protective Teflon tubing length is 2.15 m in a 2 m armor cable jacket. Customers should contact EOT regarding other fiber requirements.
b Unless otherwise specified by customer
c Insertion loss of light through fiber cladding is not included in the insertion loss specification.
d Case temperature ≤50 °C
* Patent pending
NOTE: It is recommended that the isolator be attached to the laser enclosure using a compression fitting that secures only the outer, metal reinforced jacket. The inner PTFE tube is meant as an abrasion barrier for the optical fiber and should be allowed to move freely with the fiber.
