Since the laser diodes only put out one wavelength of light, the beam bends but does not split or diffuse.

The control system is build around the simple Arduino shield shown to the right, which uses simple 74 series logic to send TTL control signals to the laser diodes used in his rig.

Jon Bumstead has created an awesome Arduino powered 13 note midi harp after receiving funding from the optics group Spectra at Washington University in Saint Louis.

The MicroSlice laser cutter and engraver offers a working area of 50 x 50mm and is capable of cutting through paper and engraves wood & plastic using a 100mw Red Laser Diode, like you’d find ...

Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser wavelength to just Δ11.6nm – 0.10nm/°C”, said the company. “This makes it possible to narrow the ...

The Arduino illuminates (blasts) the target using an inexpensive laser diode mounted on a servo motor. Interesting applications of applied math include computing distance based on sonic travel time, ...

The laser diode outputs can tolerate voltages up to 10 V to make it possible to use laser diodes with a high forward voltage. In addition, power control for the laser diodes is performed by ...
