ABSTRACT:
In order to suppress laser noise, a semiconductor laser oscillating in a single mode under direct-current drive is driven by a signal with a high frequency current superposed on a direct current. In particular, the laser is driven to be brought into continuous wave pulsed oscillation at a pulse width of at most 1.2 ns to achieve the desired noise suppression.
