Our 561nm diode laser went bad on a confocal system, and it has taken 2
months to obtain a new one. I pose four lines of questioning to the list:

1) Have people tried refurbishing old lasers? How did they perform?
2) Do you believe that refurbished lasers are a good value at half the
price of new replacement?
3) Do lasers degrade while sitting unused on a shelf? (Should we have a
refurbished laser on hand for next time, or should we wait?)
4) Is two months typical for ordering a laser without a service contract?
Are lasers in that short of supply?

Thanks in advance to all responders.
