THE ULTIMATE MEASUREMENT AND CONTROL TOOL FOR ULTRAFAST LASER SYSTEMS
AND HOLLOW-FIBER COMPRESSORS

d-scan is an inline, compact and high-performance device for the simultaneous measurement and compression of even the most demanding ultrafast pulses. d-scan can be used either as a standalone system or integrated with existing optical pulse compressors. It handles broadband oscillators, amplifiers, OPAs and hollow-fiber compressors.

Coupling your beam into the d-scan is easily achieved in less than one minute and a full measurement takes less than 10 seconds. The resulting d-scan traces are very intuitive and a proprietary retrieval algorithm provides fast and accurate retrieval of the full electric field of your compressed ultrafast pulses.

Oscillator

Few-cycle Ti:Sapphire oscillator: Measured (a) and retrieved (b) d-scan traces. (c) Measured spectrum (black) and retrieved spectral phase (red). (d) Retrieved temporal profile (black) and phase (red). Pulse duration is 5.5 ± 0.1 fs (FWHM).

Hollow Fiber Compressor

hollow-fiber-compressor

Single-cycle hollow-fiber compressor: Measured (a) and retrieved (b) d-scan traces. (c) Measured spectrum (black) and retrieved spectral phase with standard deviation (red). (d) Retrieved temporal profile for the wedge insertion that minimizes the pulse duration, corresponding to 3.2 fs (1.3 cycles at 740 nm).
