PULSE POWER SUPPLY UNIT WITH MICROCONTROLLER CONTROL FOR A LASER DIODE ARRAY PUMPED ERBIUM-YTTERBIUM LASER
SINOPSIS
The work is devoted to the design of a power supply unit with microcontroller control for a pulsed diode system for pumping an active medium of an erbium-ytterbium laser. The power supply provides a broad adjustment of the current pulse shape for flexible tuning of the laser operation mode. We used the scheme with MOSFET operating in the linear zone powered by a storage capacitor. In this case, the laser diode array connects to the source circuit of the MOSFET, which allows to power lasers in which the cathode of the laser diode array connects to the ground. The described in this paper power supply provides high parameters of the output pulse, a low level of electromagnetic interference, and has a system of protection against failure of laser diode arrays.
