Temperature Influence on Spectroscopic and Laser Properties of Er:YLF Crystal

Popis výsledku v původním jazyce

The spectroscopic and laser properties of Er:YLF crystal, that is appropriate for generation at 2.8 μm, in temperature range 80 - 300 K are presented. The sample of Er:YLF had face-polished plan- parallel faces without anti-reflection coatings. During experiments the Er:YLF was attached to temperature controlled copper holder and it was placed in vacuum chamber. The transmission and emission spectra together with the fluorescence decay time were measured depending on temperature. The tunability of laser at 80, 200 and 300 K was tested using MgF2 birefringent filter and several laser lines in wavelength range from 2709 nm to 2860 nm were observed. In pulsed regime, the highest slope efficiency with respect to absorbed mean power 23 % and the maximum output energy 12.5 mJ were reached. The laser radiation generated by Er:YLF laser (2.81 μm) is close to absorption peak of water (3 μm) thus this wavelength can be use in medicine and spectroscopy.
