Product Description

This multi transverse mode M140 laser diode component is pressed fit mounted in an aluminum housing and has an aluminum mountable heat-sink.  The laser is set in the heat sink with thermally conductive paste.  The front of the component contains a adjustable high efficiency glass focusing lens for the laser output.  The laser has an ABSOLUTE MAXIMUM of 2W and should only be run at this level for very short times.  Additional cooling techniques would be advisable if you want to run for extended periods at this high power.  1 amp at 1.2W will allow for longer “on” times and will not degradate the laser as quickly.  Thermal issues are the number one reason for catastrophic failure of the laser.  while the mounting case provides heat sinking capability for the laser diode, it is up to the consumer to make sure the laser is operating effectively within these limits.

Output Conditions

The laser diode output will vary depending on the temperature.  While there is a housing and a small heat sink, it is recommended that the diode not be on for long periods of time.  The laser diode will also require more current to maintain the same amount of output power as the diode degrades.

Static Precautions

Take precaution when handling laser diodes as they are a static sensitive devices.  There is a built in protection in the diode which can help in normal static situations but it is no guarantee.  Static electricity and electrical surges will degrade the performance of the laser diode.

Laser Safety

Laser light can cause damage to eyesight and skin if proper laser safety is not used.  Always wear the appropriate laser goggles to prevent any laser light, either directly or indirectly to contact the eye.  Never expose skin directly to laser radiation.  Focused light will increase the safety hazard.
