| Abstract | ||
| This paper describes the design and construction of a semiconductor laser diode, driving (400) mW to (1000) mW with fixed wavelength of (808) nm. The electronic circuit is delivering up to (1400)mA to a laser diode and capable of keeping the temperature of the laser diode fixed at (25) 0c.To protect the laser diode from failure this circuit includes ,a voltage protection circuit which keeps the voltage of the laser diode around (2.1) V and temperature protection not to exceed (30)oC. This circuit can keeps the temperature of the laser diode at 25 0c yet the ambient temperature between (–05 - + 50) 0C. | ||
