The development of wide range continuously tuhable lasers is an important problem of quantum electronics. A great achievement in this field has been made by color center lasers. This paper is devoted to the development of powerful widely tunable solid state laser systems. Our earlier results in obtaining tunable lasing in the near IR region, in LiF crystals with F; and F. color centers finally resulted in the development of the pulse-pe-riodic computer scanned tunable color center laser “MALSAN-201”. The device has two independent optical channels working simultaneously (Fig 1). © 1989 SPIE.
