Hi All,
here now my, at the moment, strongest Selfmade Laser with aktiv cooling system :beer: For the Housing i used a full Aluminium Hand-Gas-Pump which used in the industry to locate dangerous chemicals in low concentration. The M140 LD is mounted in a cooper Heatsink with the M9x0,5 Fine thread like in the Aixiz Moduls for Collimator Lenses and fixed in the Aluminium-Head of the Pump.
The piston of the pump was modified to insert a 12V-fan and the bottom-cap was milled to fix the fan and close the Tube. The Alu-Head was drilled around the Lens...so the cold Air is cooling the Diode and the Driver behind. The Driverboard is selmade with a LM317 and Alu-Heatsink, the Poti-Resistor is designed for a output current of 1400mA, so the Power can controled from Zero to 1,4A The Voltage Source is a 2S-LiPo (7,4V)with 5200mAh and 30C, the Fan startet with connecting the LiPo, the output over the 2-way-switch (on)-out-on.....that`s it. One hour non-stop burning is without problems
