Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

In low power laser diode modules the designer has the option to use the classical discrete solution or take advantage of fully integrated driver ICs. Often the component cost is the only driving ...

[SilverJimmy] already had a full-sized 50 watt laser cutter, but he decided to try his hand at putting together something smaller and microcontroller-driven. The result is this adorable little ...

See this diagram,I've been told the the proprietary drivers offer some extra protection from very short spikes (on power up and shutdown) in the current which laser diodes are very sensitive to and ...

It's definitely not the most efficient way to get a clock on your wall, or the cheapest, but if you're looking for a clock that turns heads, looks cool, and is a great starter project if you're ...

If you have ever wanted to create your very own laser tripwire grid like in the movies to protect your valuables possessions, buildings or outhouses. You might be interested in a new Arduino ...

The compact LD15CHA Laser Diode Driver delivers industrial grade power up to 15 A and 28 V output with bandwidth up to 600 kHz. The clipping current limit ensures the limit will never be exceeded, ...

[Robi] and [Kathy] from elecfreaks have put together a how-to article about a Laser Piano they just built. Instead of keys, the user breaks beams of laser light to trigger the sounds. Several laser ...
