Study of the spectral and angular characteristics of laser action by rhodamine 6G solutions in a short cavity
An experimental and theoretical study has been made of the spectral and angular characteristics of a laser with an ethanol solution of rhodamine 6G, pumped with the second-harmonic radiation of an LTIPCh-6 laser, as a function of the spacing of a Fabry-Perot interferometer used as a cavity laser. It is shown experimentally that when the cavity is short, the radiation of the laser studied has a distinct spectral and angular structure which is determined by the length of the cavity and is independent of the reflectancies of the cavity mirrors, activator concentration, or power of the exciting radiation. Good agreement is shown to exist between the experimental and theoretical results. It is concluded that the character of formation of the spectral and angular radiation characteristics of a dye laser is determined almost entirely by the properties of the Fabry-Perot interferometer used as the cavity.
