Analysis and simulation studies of the longitudinal mode behavior of two-section coupled-cavity lasers in the steady-state are presented. The laser is analyzed with a resonance amplifier model and the scattering matrix formulation. The mode selection property of this laser is explained in terms of the wavelength-dependent effective reflectance. Expressions(More)
We present an optical detection method for the fundamental vibrational mode of a tuning fork crystal oscillator in air. A focused He/ Ne laser beam is directed onto the edge of one vibrating tine of the tuning fork; its vibrating motion chops the incoming laser beam and modulates the intensity. The beam with modulated intensity is then detected and(More)
