Clarification on Laser Dye Concentrations
DOI: 10.1063/1.1510312
In Physics Update for the February 2002 issue of Physics Today (page 9 ), one item states, “In most dye lasers, the dye concentration cannot go above a millimole/liter without quenching the fluorescence.” Subsequently, lasing at a concentration of 9 mmol/L is highlighted as an achievement by the authors. 1 It should be noted that dye concentrations of several mmol/L, sometimes up to 10 mmol/L, have been known for a long time in the field of laser-pumped dye lasers. 2
