Abstract

Single frequency operation of a diode pumped Er:YAG laser at 1.64 micrometers was achieved first time with a new type of halfmonolithic lasers in a cleaved coupled cavity (C3). A single frequency Er:YAG-Er:glass-sandwich laser in C3-design was realized as well. Single frequency operation of the Er:glass laser is also achieved with a thin metal film and a tilted Fabry-Perot etalon as mode selective elements. The tuning range of Er:glass can be extended up to 1560 nm by a special mirror coating. Eye safe erbium lasers are very important for different applications in optical communication and lidar techniques, e.g. due to their coincidence with the attenuation minimum of glass fibers at 1.55 micrometers (Er:Yb:glass laser) and with the methane absorption line at 1.64 micrometers (Er:YAG laser).
