Abstract
A rhodamine 6G (RH-6G) dye laser was actively mode-locked by synchronous pumping using a frequency-doubled mode-locked Nd3+ glass laser. Output light intensities and polarization were measured as a function of the pumping power and dye concentration. Dye laser pulses were observed with a streak camera of 8 ps resolution. The laser pulse width decreased down to the minimum value of 18 ps as the degree of polarization increased up to the maximum value of 0.75. The addition of DODCI as a saturable absorber enhanced the degree of polarization up to 0.9.
