And a few other things!
Some interesting info in this PDF.
SONY LASER DIODE GUIDE
Here are some highlights...
Temperature is one of the primary factor affecting reliability for semiconductor laser diodes. As the temperature of the diode and the surrounding area increases during use, the rate of degradation increases exponentially.
For every 10°C increase in room temperature lifetime decreases by about a factor of 1/2.
Tolerance to soldering heat: Temperature 265°C for 5 seconds
(Although it says this elsewhere: "Keep the solder iron (30W) tip temperature less than 260°C and do not keep in contact for more than 10 seconds.)
Natural fall: Height 75cm Maple plank strike surface 3 times
Note that deposits or dust on the window glass of a laser diode could cause deterioration of the laser diode performance. The following practices are recommended.
1. Do not touch the window glass with bare hands.
2. Use care to prevent damage to the window glass by tools or other objects.
3. When dust deposited on the window glass is to be removed with an air gun, short circuit the leads or use a moss pack covered with a conductive bag.
This was written in 2000, so some of it (like soldering temp) may be outdated.
Note pages 68-69. That would be a neat soldering station!
