How can I improve the lifetime of my laser diode module?

Operating the diode at the low end of the temperature range can extend its lifetime. High operating temperatures are often the reason for laser failure. The lifetime of a typical module will be cut in half for every 8°C increase in temperature. Note the specific operating and storage temperature ranges for each specific laser diode module. Power supplies should also be selected to run at the lowest voltage value in order to extend lifetime. Heat sinks are recommended in order to transfer heat away from the laser diode module and must be used if operating near maximum voltages. The heat sink should be mounted toward the front of the module (this is the location of the diode) and a 1-inch outer diameter sleeve is typically sufficient. Our laser diode pivot mount offers both heat sinking and alignment features. Handling can also effect lifetime and performance. Although our laser diode modules offer varying degrees of ESD protection (Electro-Static Discharge), high-energy discharges or energy spikes can cause permanent damage. Diode modules typically have a lifetime of 10-20,000 hours compared to the typical 100,000 hours of the raw diode component. Please note that due to the construction of green diode-pumped solid-state laser modules, they are extremely sensitive to temperature.
