Abstract
An infrared sensitive synchroscan streak camera for use in the wavelength region of 1.0 to 1.6 μm is described, including system configuration, absolute photocathode sensitivity, system dynamic range, and its application. Linear (y=1) dynamic ranges of more than 103 at 1.3 and 1.5 μm wavelength have been demonstrated to confirm a single photon reaction in the photocathode at the practical power density level, using ultrashort light pulses from laser diodes. Applications of the system for direct and linear measurement such as picosecond time-resolved spectroscopy of diode laser pulses at 1.3 and 1.5 μm wavelength are also discussed. The system works in single-shot mode as well as synchroscan, by changing a plug-in. This new technique can be widely utilized for direct, linear, real-time and multichannel measurement of ultrafast optical phenomena in the wavelength range of 1.0 to 1.6 μm.
