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 ...

The circuit requires approximately 6 cm 2 of board space and has no reverse-polarity or failure protection for the laser diode. The start-up time of this discrete solution is approximately 20 ms.

Instead of sending radio waves bouncing all over creation, this uses the focused light of a laser to transmit audio. In the image above you can see the silver cylinder which houses the laser diode.

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 ...

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 ...

Lawmakers remove ‘revenge’ tax provision from Trump's big bill after Treasury Department request The stock market is nearing a record high. Here's why. Brad Pitt opens up about embarrassing career ...

Hybrid laser diode chip In their new study, detailed in Nature, the researchers, led by EPFL’s Tobias Kippenberg, assembled a hybrid device by integrating a distributed feedback laser and a silicon ...

The MOGbox DLC-202 laser diode controller from MOGlabs is the world's first all-in-one controller for driving and frequency locking an external cavity diode laser. Every model includes: All this comes ...

The inexpensive LSC-035 driver was developed for N type cw laser diodes with a maximum operating current of 300mA. The wide-ranging supply voltage of up to 15V allows the operation of blue, red, and ...

Small is the new big. China, Taiwan, and United States physicists have teamed up to develop the world’s smallest semiconductor laser. This emerging photonic technology breakthrough has potential ...
