Paper Abstract

The paper presents a construction and some investigations results of a new driver for quantum cascade (QC) lasers. The driver is designed to control pulse and CW mode QC lasers. For both laser mode operations, there is the possibility to set a laser current in the range of 0.1 A - 3 A and pulse duration of 30 ns at the frequencies to the level of 25 MHz. The stabilization of the temperature in the range of 50°C ÷ -30°C with accuracy of 1.5 K is also achieved. A full synchronization with external pulses makes the driver very useful in a construction of a free space optical transmission system and of a laser spectroscopy setup.
