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 ...

Interfacing laser driver circuits with commercially available laser diodes at high data rates can be a complicated and frustrating task. This application ...

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, ...

With the aid of an integrated monitor photodiode such laser diodes provide 5mW or 7mW output power with stable operation up to 70°C. The devices can even be offered in a very small 3.3mm TO-can ...

An auto laser power control (APC) circuit for optical communication laser diode driver (LDD) is proposed. The APC compensates the fluctuation of (laser diode) LD laser power, maintains the output ...

A wideband multiple resonance small-signal laser equivalent circuit model is presented to improve optoelectronic circuit design accuracy. Two important laser diode characteristics, such as input ...

The laser driver consists of a high-speed modulation driver, laser-biasing block, and a pulse-width adjustment control circuit.

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.
