High power laser diode driver based on power converter technology. This paper describes the design of a high speed semiconductor laser diode driver designed for driving mW to W diodes at full optical power modulation up to frequencies of 10 MHz. The duty cycle of the modulation may be varied. A switching power-converter based current source allows a higher power delivery efficiency to the diode than in previous designs, allowing for a more modest power supply and dissipation www.doorway.ruted Reading Time: 10 mins. High power laser diode driver based on power converter technology Abstract: This paper describes the design of a high speed semiconductor laser diode driver designed for driving mW to W diodes at full optical power modulation up to frequencies of 10 MHz.

For low power laser diodes, a regulator operating amplifier which controls the current flowing through the laser diode via a sense resistor can be used. A simplified circuitry of a low power laser diode driver is shown in Fig. 1. High power laser diodes on the other hand. This paper describes the design of a high speed semiconductor laser diode driver designed for driving mW to W diodes at full optical power modulation up to frequencies of 10 MHz. The duty cycle of the modulation may be varied. A switching power-converter based current source allows a higher power delivery efficiency to the diode than in previous designs, allowing for a more modest.

Depending on the application and power level, the requirements on laser diodes drivers In case of high-power diode drivers, it is of interest to have a. Fast rise time to high currents in a load such as a laser diode array is achieved by connecting an inductor between a power supply and an end of the diode.
