Laser Quantum has released the ASOPS Engine, an advanced time-domain spectroscopy system that offers extremely fast acquisition speeds of up to 20kHz and excellent time-resolution; significantly below 60fs for 1GHz lasers, and 100fs for 84MHz lasers.
The ASynchronous OPtical Sampling (ASOPS) technique enables fast scan rates and long measurement windows whilst maintaining excellent time resolution, ideal for a range of applications including ultrafast time domain spectroscopy and high-resolution terahertz spectroscopy. The ASOPS Engine provides benefits that cannot be achieved using conventional time-delay spectrometers.
The ASOPS engine is comprised of two femtosecond lasers, a TL-1000 ASOPS for offset frequency stabilisation, an optical trigger unit, a high-speed balanced optical photo receiver, a PC housing the data acquisition card, and HASSP-Scope software for the measurement and analysis of time-domain data.
