Abstract

Certain color centers in alkali halide crystals are well suited as active materials for tunable lasers in the near infrared region. With FA(II) centers in KCl:Li and RbCl:Li and FB(II) centers in KCl:Na and RbCl:Na the spectral range from 2.25 μm to 3.05 μm can be covered so far [1,2]. Considering threshold values, output powers, tuning ranges and efficiencies color center lasers (CCLs) are essentially comparable with dye lasers. Comparing the frequency behavior of the above mentioned lasers with other tunable sources we find the advantage of CCLs in the ease of single mode operation and in the emission linewidth which is remarkably small [3]. On the other hand the mechanical system of a CCL is as simple as that of a dye laser [4]. Therefore CCLs seem to be very attractive for applications in laser spectroscopy and chemistry in the near infrared.
