To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply voltage, thus protecting it against such transients (Figure 1). When the negative supply rail ...

The value of R1 is determined by the maximum laser current required (in this case, 250 mA), adjusted by the laser diode's typical forward voltage of 2.0 V as given on the datasheet. Solving for R1 ...

Good design drives diode performance. 12 Jan 2004. If you plan to buy a laser diode driver, make sure you check the specifications with care. ... if the current source controls are digital, as most ...

To send a group of this kind of optical pulses, the laser diode driver needs to deliver high-speed, modulated pulse current to a laser diode. One of Intersil's conventional laser-diode drivers, the ...

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 ...
