Optically stabilized diode laser using high-contrast saturated absorption

Cuneo, Christopher J. 20 May 1994 (has links)
Doppler-free saturation spectroscopy in an optically thick atomic vapor is used in an optical-feedback configuration for two semiconductor diode laser systems. One laser system consists of an unmodifed, commercially available diode laser. The other laser system consists of a diode laser initially stabilized by optical feedback from a diffraction grating. In both cases a portion of a 780-nm diode laser beam passes through a heated rubidium cell and is retroreflected back to the laser. The optical feedback causes the laser frequency to be stabilized to a hyperfine transition within the Rb D��� line. The linewidth of the laser is also reduced as a result of the optical feedback. / Graduation date: 1995
