You can get a red laser diode pretty cheap these days—as cheap as £1 in fact. [Beamer] had purchased one himself, but quickly grew bored with just pointing it at the walls. He decided to figure ...

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 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 ...

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 ...
