A tunable single-mode laser is obtained by using a weakly coupled cavity structure involved
in a coaxially packaged Fabry–Perot laser diode. The cleaved end facet of the coupling fiber …

An external-cavity (EC) quantum cascade (QC) laser using optical feedback from a partial-
reflector is reported. With this configuration, the otherwise multi-mode emission of a Fabry …

Optical-pum**-induced population-grating transfer between hyperfine levels of the cesium
D 2 line is observed through four-wave mixing in a sample of cold atoms. Diffraction …

We have employed a sample of cold cesium atoms in a magneto-optical trap to study
nonlinear spectroscopy and four-wave-mixing optical phase conjugation using a noncycling …

Semiconductor diode lasers are currently used in numerous applications. Optical feedback
and optical injection are known to induce a diverse range of effects, which can be beneficial …

We present the theory behind and discuss experimentation on the spectral control of a laser
diode with a Michelson external cavity. This structure is advantageous in terms of variable …

Much of this book is devoted to the nonlinear dynamic behaviour that results when optical
feedback from an 'external reflector'is introduced into a semiconductor laser resonator …

Quantum cascade (QC) lasers have emerged as a viable laser source in the mid-infrared
spectral region due to their large wavelength design space that covers important absorption …

Without additional frequency selecting elements, most lasers utilizing linear resonators emit
at several axial modes. A resonator operating in a single transverse mode, exhibits a …

This paper describes the fabrication technique and operating characteristics of tunable
sources on the basis of III-V with central emission wavelength 835nm and 980 nm. The laser …
