Abstract

Lasers generating at 1.5 µm wavelength attracted much interest due to their many potential applications. In the last two decades many papers have been published demonstrating pulsed as well as continuous wave (cw) operation of such lasers [1-5]. One of the most interesting application is telemetry where these lasers are used in range-finders and lidar systems [6, 7]. In such application high peak power, high quality of the output beam and small laser dimensions are the most important parameters. The last two parameters are relatively easy achievable in case of microchip lasers. However high peak power is difficult to achieve which convinced many scientist to conduct research in the field of different active media, saturable absorbers and different configurations of these two elements. The mostly used configuration for pulse generation at 1,5 µm is glass doped with erbium and ytterbium as active medium passively q-switched with MgAl2O3 doped with cobalt.
