Vertical External Cavity Surface Emitting Lasers (VECSELs) VI.
We present a comprehensive characterization of semiconductor gain and absorber devices utilizing novel measurement techniques. Using a 20fs probe laser, a time resolution in the few femtosecond range is achieved in traditional pump and probe measurem
