By coupling a cw GaA1As-diode laser to an external resonator with Fabry-Perot etalons as dispersive elements, emission was reduced to a single-axial mode of 32-MHz width. The wavelength could be coarsely tuned over a spectral range of over 10 nm. Fin

A model of a regenerative resonance amplifier has been used to describe Fabry-Perot GaAs diode lasers coupled to short external resonators. The optical gain and the equivalent input of the resonance amplifier are controlled by means of appropriate ra

The light output and the electron density within the active layer of a semiconductor laser have been calculated from the steady state solution . The assumed rate equation model takes into account the spontaneous emission into the lasing modes. Simple

Uncoated GaAs diode laser of different structures are coupled to external spherical mirrors. The emission characteristics of these systems are investigated. Mode selection effects are observed and single-mode operation may be achieved in the hemisphe

(Ga,Al)As CW diode lasers with a linear light output L versus pumping current J characteristic have been coupled to an external optical cavity. This coupling is shown to induce nonlinearities in the L(J) characteristic. The light output of external-c

The light output powers of a semiconductor laser diode within an external cavity and of two optical coupled diodes are evaluated as a function of the system parameters (drive currents and coupling coefficient). The calculations are based on a rate eq

Two diode lasers have been coupled by means of conventional optics. The coupling coefficient has been altered by inserting additional filters into the light path between the two diodes. The power output and the spectral behaviour of both diodes have

The laser emission of a cw diode laser coupled to an external cavity is self‐pulsing at a frequency of 3–30 MHz, that is, two orders of magnitude lower than the resonance frequencies of the external cavity (typically 0.5 m long). The low‐freque

The deformation behavior of pulsed double−heterostructure diode lasers at both mirror and contact surfaces was investigated by means of an interferometric technique. The diodes, which were only supported by the pressure of a wire connection, showed
