Progress in technology and construction of diode-pumped laser made in the 80's caused renewed intereset in diode pumping of active media of solid-state lasers (DPSSL -Diode Pumped Solid State Laser) and next their rapid development. At present, DPSSL are commonly applied in medicine and industry.The paper presents advantages of such excitation and significant improvement in generation efficiency, longer service life of devices, smaller dimensions of quantum generators and theirs power suppliers. Special attention is paid to the possibility of application of new active media (new neodymium doped hosts), including ytterbium (Yb) doped media, that have perfect functional parameters with diode pumping. Fundamental configurations of active media and their excitation methods are described. A "slab" type geometry used for high-power lasers is distinguished. It is shown that construction of, so-called, microlasers is possible when diodes are used as pumps of solid state lasers. Microlasers can generate strictly monochromatic radiation (i.e.,generate only one longitudinal mode). These lasers can be used for rangefinder transmitters and radars with heterodyne detection - new type devices applicability range of which is difficult to predict. Microlasers can be also used as frequency and length standards. A group of fibre lasers is considered and their unusual possibilities are described, among others generation of beams of high quality (M² ~1) and high-power (1 kW). The examples of construction of high-power DPSSL (3,5 kW) are presented.
