Temperature dependence of gain in cw alexandrite laser
Abstract
The temperature dependent behavior of a cw alexandrite laser has been measured at several wavelengths. Starting from room temperature the output power increases with rising temperature and reaches a maximum at a temperature depending on the laser wavelength. These results are attributed to a combined effect of the ground state and excited state absorption. The temperature and wavelength dependence of the excited state absorption cross section is deduced from laser output power measurements.
