How are these red diode lasers cooled? Are they mounted on a thermoelectric
header?

We have a 1 yr old FACSCalibur on its THIRD red diode laser from a THIRD
supplier.  The first lasted for 200 hr, the second for 2 hr (as in two
hours), and the third has been up and running for 30 minutes.  I would call
this a reliability problem.
