Title: Frequency Characterization of an External-Cavity Quantum Cascade Laser at 4.5 υm using a Frequency Comb
Published: January 25, 2012
Abstract: We measure the frequency noise spectrum of a free-running external-cavity quantum cascade laser at 4.5 υm through sum frequency generation with a fiber frequency comb.
