Semiconductor Microlaser Linewidths

Physical Review Letters, 1994
Semiconductor microdisk laser linewidths are measured for cavity volumes near a cubic wavelength. The linewidths remain near the subthreshold values for pump powers well above threshold in agreement with a microscopic theory that includes the coupled dynamics of the optical emission and the nonequilibrium electron-hole gas in the cavity.

Linewidth narrowing of polaritons

Physical Review B, 1996
Polaritons are formed when the electromagnetic field couples to excitons in a semiconductor. In their high-quality semiconductor quantum microcavities, Fisher et al. observe an unexpected decrease in the polariton linewidth (the full width at half maximum) near resonance.

Linewidth and writing resolution

2016
This chapter introduces the concept of linewidth and writing resolution in direct laser writing (DLW) lithography. The experimental factors controlling these two parameters are mainly the wavelength of the laser, the numerical aperture of the objective lenses, and the mechanical strength of the photoresist.

Phase distribution and linewidth in the micromaser

Physical Review A, 1993
The phase distribution function (after Pegg and Barnett, Phys. Rev. A 39, 1665 (1989)] is calculated for the micromaser and the lowest modal phase diffusion constant is compared to the linewidth calculation of Scully et al. [Phys. Rev. A 44, 5992 (19911].

Commutation relations and laser linewidth

Physical Review A, 1990
The waves reflected from a resonator must obey the commutation relations of waves in free space. This fact alone, regardless of whether the medium in the resonator is linear or nonlinear, imposes commutation relations on the internal noise sources. The minimum linewidth of an oscillator can be derived from this fact alone.

Subhertz-linewidth Nd:YAG laser

Optics Letters, 2004
Light from a Nd:YAG laser at 1064 nm is independently stabilized to two Fabry-Perot etalons situated on separate vibration-isolation platforms. A heterodyne beat measurement shows their relative frequency stability to be at the part-in-10(15) level at 5 s and the relative linewidth to be less than 1 Hz.
