    mine is not pulsed is cw so maybe not needed optical isolator ?
    or cw needs also optical isolator ?

    ... all my "exploded" IPG-fiberlasers were CW-types without isolators ... but too, haven't seen a CW equipped with one yet

    So why IPG delivers these types of lasers without optical isolator ?
    What is the head at the end of optic fiber ?

    ... with the CW-Types its only the collimating lens ... with the pulsed it's additionally the optical isolator-"Box" in the middle ...

    It seems, for CW-laser the optical isolator is either not working good enough, or they're meant for a more complex setup in the toolhead ... while the pulsed types are used mostly "as is" inside galvo-heads ...
