I have a question concerning red diode lasers that falls in with this discussion. I have a slightly over one year old FACSCalibur with a red diode laser. For the last month (right after the instrument went off of warranty) the diode laser has been going off and on for about a hour after which it runs beautifully. I've spoken to BD and they have no idea what is going on. Any information would be greatly appreciated. Also, does turning the diode laser off when it's not needed prolong it's life? Thank you, Dixie Polakoff FACS operator Protein Design Labs (510) 574-1528 Alice.L.Givan@dartmouth.edu writes: > >Hi Flowers, >What are people's experiences with red diode lasers?
