Fiber Optic Laser Diode

An optical isolator or optical diode is an optical component which allows the transmission of light in only one direction it is typically used to prevent unwanted feedback into an optical oscillator such as a laser cavity.

Fiber optic laser diode. The operation of some of the devices depends on the faraday effect which in turn is produced by magneto optic effect which is used in the main component the. The pump laser is focused into cladding that sits around the fiber core as the fiber core itself is too small to have a low quality diode laser focused into it. Thorlabs specializes in the building blocks for laser and fiber optic systems. Other fibers and fiber lengths are available upon request.

A red 635 nm and a green laser diode 520 nm are coupled on a common fiber. The ibeam smart pt as well as the multi laser engine ichrome xle cover the range from 375 785 nm and provide a. The rp photonics buyer s guide contains 74 suppliers for fiber coupled diode lasers. The fiber end can either be bare or equipped with all readily available fiber optic connectors during production.

By pumping the laser into the cladding around the core the laser is bounced around inside and every time that it passes the core more and more of the pump light is absorbed by the core. From optomechanical components to telecom test instrumentation thorlabs extensive manufacturing capabilities allow us to ship high quality well priced components and devices for next day delivery. Depending on the integrated laser diode cw or pulsed output powers of up to 120 mw from a 9 125 single mode fiber can be achieved.
