Description
Summary:The authors report on the development and phase locking of a frequency agile laser. The use of a simple unbalanced Mach-Zehnder interferometer together with a wideband phase-locked loop permits to control very fast frequency chirps (up to 3 GHz in 5 μ s ) with an excellent precision (frequency error less than 100 kHz ). The servoloop could be applied to many tunable lasers.
