“…A QCL can provide at least 3 orders of magnitude higher power per self oscillation lines of a small oscillator, thus relaxing the requirement of the roundtrip gain and the number of roundtrips in the seeded oscillator, thereby improving power output and stability. The theoretical prediction of Fig.10 was recently confirmed by QCL multiline seeded pulses in a large slab amplifier (Nowak, 2011).…”
