Abstract: Results are presented of an investigation of passive Q switches for Nd³⁺ lasers based on a new group of alcohol-soluble tricarbocyanine dyes. The advantages of the new switches over the familiar dye № 3955 solution in terms of photochemical stability, energy efficiency, and relaxation time are indicated. It is shown that switches based on alcohol solutions of these dyes give a high degree of spatial homogeneity of the beam energy over the total cross section of the active zone. The duration of picosecond pulses emitted from lasers with this type of switch is 6–12 psec.
