Turnkey Laser Diode Mounting Kits for CS Package Now Available
Electrically isolating laser diodes used to be an engineering task. The industrial standard CS mount laser diode package for diode pump lasers is electrically hot; when mounted to laser cooling modules or cold plates, the laser diode must be electrically isolated to protect the laser. In the past, individual end users of laser diodes do all the isolation solutions themselves, and it takes engineering effort to define, design and procure the necessary components. Elite Thermal Engineering is now offering standard diode isolation kits that is in stock or can be provided within 2 weeks if it is out of stock.
The diode mounting kits includes one aluminum nitride plate and 4 nylon shoulder washers for mounting CS mount or equivalent diodes (such as Jenoptik's JOLD packages) on cold plates. Indium foils for thermal interface is also available as an option. Belleville washers for maintaining constant pressure to the thermal interface are also available as another option.
The aluminum nitride plate is .635mm thick, 25mm x 25mm with 4 through holes that match the diode mounting patterns. The nylon shoulder washers fit in the CS mounting holes and are good for M3 screws. The standard kit only cost $21.49 each at single quantity.
The aluminum nitride plate offers very high thermal conductivity while providing electrical isolation between the diode and cold plate; the nylon washers isolate the metal screws from the diode package. Elite Thermal Engineering also supplies silicone-free high performance thermal interface materials that can be used between the aluminum nitride plate and diode, and between the cold plate and aluminum nitride plate.
The nylon shoulder washer does tend to creep over time. Therefore Belleville washers or other kind of spring mechanism to maintain positive pressure is recommended. Elite also offers creep resistant PEEK shoulder washers upon request for more demanding applications.
