Investigation of laser photodetachment of rhodamine 6G ions from adsorbed layers of different thickness

An experimental study was made of the photodetachment of rhodamine ions deposited in the form of layers of different thickness on a tungsten substrate. The radiation source was a laser emitting ultrashort pulses at the wavelengths of 1.06, 0.53, or 0.26 μ. In the case of a submonolayer the formation of rhodamine ions was a thermal process.
