Abstract

We have examined a dye concentration dependent laser threshold for rhodamine 6G in methanol under weak N 2 laser excitation (337 nm), between 5 x 10 -4 and 1.5 x 10 -2. The results are analysed with consideration of the penetration dependent diffraction loss in the resonator. The behaviour of the threshold exciting intensity of rhodamine 6G in methanol against concentration pumped by a 530 nm light source is also discussed.
