Název v původním jazyce

Er,Pr:GGAG spectroscopy and laser characteristics at 3 μm in temperature range from 80 K to 300 K

Popis výsledku v původním jazyce

The spectroscopy and laser characterization of Er,Pr:GGAG crystal was carried out in the temperature range 80-300 K. The Er,Pr:GGAG was pumped by a fibre-coupled laser diode radiation (1 ms, 20 Hz, 962 nm). The transmission and fluorescence spectra together with the fluorescence decay times at the upper (4I11/2) and lower (4I13/2) laser level were measured in 80-300 K. The fluorescence decay time of manifold 4I11/2 is slightly increasing with rising temperature from 325 µs (80 K) to 341 µs (160 K) and then its decreasing to 295 µs (300 K). The tunability of emitted laser wavelength at 80 and 300 K was tested using MgF2 birefringent plate, and several laser lines at 2874 nm, 2832 nm, 2805 nm, 2718 nm, and 2702 nm were obtained. The laser radiation generated by Er,Pr:GGAG laser (2.9 µm) is close to the absorption peak of water (3 µm) and it can be tuned in a wide spectral range which could be advantageous for various applications in medicine or spectroscopy.
