Abstract
A quarter-wave retarder made by a sn;all loop of fiber on the laser pi gtail is an effective means to protect the laser from retroreflections . Suppression factors of about 20 dB have been achieved with negligibl e insertion losses, An example of application is given, A method to me asure the isolation is also presented.
