Eat Sleep Lase Repeat
I use mica washers and the kind of plastic inserts used to mount power transistors and voltage regulators.
yeah some plastic or wood.
but as above a tec would be even better and you will probably get better life out the diode

I found the rubber stuf...
try to google on GAP filler (t-global makes it)
Farnell sells the stuf

- Thermal gap fillers from 1.5 W/m K to 4.8 W/m K with and without PSA adhesive.
- Soft materials highly compressible, easy to assemble, and provide good electrical insulation.
- Shock and vibration absorber
- Typically used on electrical components, : IC, CPU and MOS, and connection between boards to enclosure walls to help heat conduction
- Typical applications include heat dissipation from LEDs, motherboards, power supplies, LCD TVs, notebooks, hubs, hand sets, memory modules, hard drives
Thanks. I will swap out the fragile mica with that stuff. I like the idea of the type with the adhesive.
I found that my CNI's driver was interfering with my other laser, so I just used a peice of mica on the uninsulated transistor. Still conducts the heat, but is not electrically conductive. If the laser itself generates some heat, a TEC can cool it for you, + its plates are made of ceramic, so its electrically isolated.
