Room-temperature operation of long-wavelength, Fabry–Perot and single-mode quantum-cascade lasers at λapprox. 16 μm is reported. Multimode emission with pulsed peak power up to 400 mW at -40 °C and 220 mW at 30 °C is demonstrated. Single-mode emission up to 60 mW peak power has been achieved at 30 °C. © 2001 American Institute of Physics.

    Abstract. The measurement of the spectral width of ultra-short light pulses using a Fabry-Perot interferometer (FPI) is investigated. It is shown, numerically and experimentally ,that the measured width critically depends on the pulse prop-erties (such as pulse shape, pulse duration, frequency...
