Summary
The Industrial Revolution in Ultrafast Science was pioneered by Coherent to bring industrial levels of reliability and stability to ultrafast lasers and amplifiers that feature cutting edge performance. Astrella is a one-box femtosecond amplifier that was designed from the ground up as part of this immersive program.
In this whitepaper, we review the three main components that underpin this industrial revolution. We then look at four research studies that have been enabled by the key benefits that stem from an ultrafast amplifier with unprecedented reliability. These include different types of 2D spectroscopy, SHG monitoring of film polarization, and transient absorption spectroscopy.
