High Power Collimated 405nm UV Laser Diode Module 350/1100mW Sharp GH04W10A2GC These modules contain a Sharp GH04W10A2GC 405nm laser diode pressed into a copper heat spreader and mounted to a steel bracket with a high performance collimating lens. These diodes are rated by the manufacturer for 350mW CW or 1100mW pulsed at 50% duty cycle, but are quite capable of being overdriven and typically produce 1.5W at a drive current of 1.1A. We've characterized these as shown in the current versus power chart. The chart also shows a typical 16X Blu-ray diode performance for comparison. Note that the wavelength shifts up to 410-415nm when overdriven. The collimating lens is single element glass asphere that is anti-reflective coated specifically for 405nm to give the highest throughput possible. These modules are pre-collimated, but you can change the beam divergence by loosening a screw to slide the lens in or out. The laser diode has a flex PCB cable attached which is wired with the center conductor to the diode cathode (ground) and the 2 outer conductors to the anode (positive). The flex also has a small reverse current protection diode mounted near the laser diode. The laser diode can be safely extracted by bending the copper heat sink. Note that the leads on the diode are fairly short. Laser diodes are extremely sensitive to static, over-current, reverse-current and overheating any of which can damage or destroy the diode without changing it's appearance. As such, we do not allow returns on laser diodes once the sealed anti-static packaging has been opened.
