Many laser diode manufacturers supply application notes which suggest control circuits to drive their laser diodes. As an example, Figure 1 shows a typical discrete APC 1 laser diode driver solution ...

In the complete circuit, Figure 4 , the ISL58837 laser-diode driver has four current-amplifier channels and their current gains are determined by the serial resisters connected to IINR, IIN2, IIN3, ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and tal… ...

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 ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and talks ...

A single laser-diode driver from Elantec Semiconductor directly drives both CD and DVD lasers, simplifying the task of combining these optical drives in a single system. Elantec's patented EL629XC ...

Contains various protection circuits such as laser diode overcurrent and short detection, thermal shutdown and photodiode overcurrent detection. The device has passed the AEC-Q100 (Grade 2) compatible ...

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 ...

Ricoh Electronic Devices has expanded its portfolio with the addition of two new Laser Diode Driver ICs targeted for laser scanning type automotive and consumer projector applications.
