Pulsed quantum cascade device assembly with active voltage pulldown |
| abstract |
A laser assembly (10) for generating a pulsed output beam (16) includes a quantum cascade device (12); and a laser driver (14A) that controls the voltage to the quantum cascade device (12) in a pulsed drive profile (950) to generate the pulsed output beam (16). The pulsed drive profile (950) includes a plurality of spaced on-time segments (952) in which the laser driver (14A) directs voltage to the quantum cascade device (12), and at least one off-time segment (954) in which the laser driver (14A) pulls down the voltage from the quantum cascade device (12). The off-time segment (954) occurs between two on-time segments (952). |
