Composition-controlled recovery time of SWIR (2-2.4 µm) GaSb-based SESAMs
{{output}}
SEmiconductor Saturable Absorber Mirrors (SESAMs) have revolutionized the ultrafast laser industry. While SESAMs are well-established in the near-infrared regime, using GaAs-wafer epitaxy, there is an increasing interest for the short-wave infrared (SWIR) regi... ...
