|Title:||Comb-assisted swept laser spectroscopy with a mode-hop free tunable external cavity QCL|
|Published:||May 01, 2012|
|Abstract:||We demonstrate sub-MHz spectral resolution of N2O absorption spectra acquired with a swept external-cavity quantum cascade laser (QCL) over 0.87 THz. The QCL frequency is monitored by sum -frequency generation with an optical fiber frequency comb.|
