Abstract

It is proposed to use laser crystals Co:MgF₂ pumped by laser radiation of 1.3 micrometers wavelength. This crystal is a vibronic laser material having a pump band with a maximum at 1.3 micrometers and a broad gain band covering the wavelength range from 1.5 up to 2.3 micrometers . The inversion lifetime is 1.3 ms at 80 K. So, it is possible to use pumping lasers operated in a free running mode. There are well-developed powerful lasers having 1.3 micrometers wavelength output. These are iodine lasers (photolytic and chemically pumped) which operated at I(²P_1/2) - I(²P_3/2) transition and neodymium solid state lasers (glass, garnets) which operated at ⁴F_3/2 - ⁴I_13/2 transition of the Nd⁺³ -ion. They have high output energy and efficiency. A conceptual scheme of the ultrashort pulse laser system of the Petawatt output power level is considered.
