【Abstract】 AbstractThis paper presents a brief introduction to a ring-cavity ultrashort pulse laser.Rh6Gand DODCI are taken as active gain medium and saturable absorber,respectivcly.Laserpulses as short as 50fS are successfully produeced with this laser through the proper chioceof some important parameters. The research interests in finding out the dependence ofsuch parameters as dye concentration is focused,dye jet thickness,astigmatic angle,pumping power upon the output laser pulse width.In addition, the role of intracavitydispersion and relative jet position within the folded mirrors have been investigated inregard to the laser operation stability.Some key factors directly affecting the laser outputparameters are understood.The useful method for further performance improvementof this kind of lasers is obtained.更多还原
