Quantum cascade lasers are versatile light sources in the mid-infrared range for molecular spectroscopy which find a wide of applications from high-resolution studies to sensing. While devices with either high power or narrow spectral linewidth have previously been reported, there is still lack combining both these characteristics particularly important precision measurements weak spectroscopic...
The first demonstration, to the best of our knowledge, of distributed Bragg reflector (DBR) and monolithic distributed feedback (DFB) lasers in photothermorefractive glass doped with rare-earth ions is reported. The lasers were produced by incorporation of the volume Bragg gratings into the laser gain elements. A monolithic single-frequency solid-state laser with a linewidth of 250 kHz and outp...
