Abstract
The optical transmission of platinum dithizonate dissolved in CCl4 was measured as a function of intensity at 6943 Å. When a 35‐nsec pulse is used for excitation the transmission increases from its low‐level value at a power density of 0.1 MW/cm2, goes through a maximum at 10 MW/cm2 and then decreases to its low‐level value at 80 MW/cm2. This material functions effectively as a passive Q switch for ruby and may provide power stabilization as well. A long‐lived cumulative bleaching effect is produced when the output from a non‐Q‐spoiled laser is used for excitation. The transmission behavior of this system at all intensities is discussed in terms of a generalized kinetic mechanism.Keywords
