Compact quantum-dot-based ultrafast lasers

Solid-state lasers that can generate optical pulses in the picosecond and femtosecond domains have progressed rapidly over the past decade from laboratory systems to an impressive range of commercial systems. Novel materials, notably quantum-dot semiconductor structures, have enhanced the characteristics of such lasers and opened up new possibilities in ultrafast science and technology. In our most recent work we have shown that quantum-dot devices can be designed to provide efficient means of generating and amplifying ultrashort optical pulses at high repetition rate rates.
