Water vapour and wind measurements by a two micron space lidar

Spectroscopy and microchip laser operation of Tm, Ho:KYW crystals with different Ho concentrations

“…Efficient compact laser sources emitting in the 2µ spectral region are in high demand due to their potential in free space applications, such as gas detection, remote chemical sensing, wind velocity measurements (Doppler-LIDAR systems) and optical communication [1][2][3]. In addition, fine tuning of the laser wavelength in the 2 µm spectral region to water absorption bands will results in strong absorption of radiation by human body tissues and makes these lasers suitable for a range of medical applications [3].…”
