Source: PicoQuant Mode-Locked Diode Lasers Diode lasers can be designed to emit light in ultrashort pulses rather than continuously. This is achieved through mode-locking techniques, where a single ultrashort pulse circulates in the laser resonator, leading to a high repetition rate pulse train. Mode-locked diode lasers can produce pulses in the picosecond regime, with pulse
