Ultrafast Gain Dynamics in a Quantum Cascade Laser

Not Accessible

Your library or personal account may give you access

Abstract

Time-resolved mid-infrared pump-probe measurements in a quantum cascade laser operating above threshold reveal gain recovery dynamics to be two-fold: relaxation within a stage on a sub-picosecond scale and transport between stages on a picosecond scale.
