Vi. Bespalov et al., CONVERSION TO THE 2ND-HARMONIC OF HIGH-POWER IODINE PHOTODISSOCIATIONLASER SYSTEM PERUN, Czechoslovak journal of Physics, 45(9), 1995, pp. 757-760
The frequency doubling of the iodine laser PERUN is described. The max
imum conversion efficiency of approximate to 55% is attained, the ener
gy of the red (lambda = 0.657 mu m) radiation is approximate to 20 J.
