Observation of periodicity multiplication in a synchronously pumped dye laser

By tuning the cavity length of a synchronously pumped dye laser, many stable operating points were observed, where the periodicity of the dye laser was an exact rational multiple of that of the pumping argon-ion laser. The multiplication ratio was also found to be dependent on the pumping laser power. Output with 14 times the pumping periodicity has been observed in the time domain. Twenty-six times the pumping periodicity has been observed in the frequency domain. This system can be used to study the phenomena of optical chaos at high repetition frequencies in the visible.
