Ultrafast laser spectroscopy uncovers mechanisms of light energy conversion in photosynthesis and sustainable energy materials
The invention of the laser in 1960 gave us the ruby laser, which generally produced chaotic
pulses of light. Six years later, in 1966, a concept called passive mode-locking applied to …
