Dear List,

I am considering placing a Faraday rotator or isolator in front of a
two-photon laser and am wondering what others have experienced with
such a configuration.

I am currently experiencing a lot of "feedback", ie return reflected
laser, that is wrecking havoc with my laser's stability. When it
senses the reflected light, it can not maintain a mode locked state
and can only lase in CW.

I'm heard that a Faraday rotator should be sufficient, but I am
wondering if an isolator is necessary to stop the reflected light
from entering the cavity of the laser source. Also, I would love to
get a recommendation for a reliable company that makes them.

Many thanks for any advice,
Ann
