We demonstrate a mid-infrared spectrometer based on a quantum cascade laser operated in the intrapulse mode coupled with a custom dense pattern multipass cell. Detection in the range of hundreds of ppm to a few percent has been achieved due to a spec

Portable and remote sensing solutions to detect the nature of gases in the air are highly demanded. In particular for instance, for the measurement of fire smoke or uncontrolled discharge on risk sites or on an accident including a vehicle transporti

Solid State Lasers XXVIII: Technology and Devices.
We have developed a fast wavelength modulated mid-IR source, especially designed for gas spectroscopy. The whole laser source is composed of a picosecond fiber laser emitting a spectrally narrow signal which can be modulated between 1028.3 nm and 102

A rapidly tunable picosecond PM ytterbium fiber laser pumps an OPO for wavelength conversion to the mid-IR. This compact and transportable source permits fast sensing of methane, and hydrochloric acid with two different detection schemes.
