Multiply resonant distributed-feedback lasers

IEEE Journal of Quantum Electronics, 1976
In this paper, we propose, analyze, and experimentally demonstrate a new type of distributed feedback laser, the multiply-resonant distributed feed-back (MRDFB) laser. For active media having broad, partially- or fully-inhomogeneous gain lines, the MRDFB laser allows colinear lasing to occur simultaneously at several preselected wavelengths.

Distributed feedback fiber Raman laser

IEEE Journal of Quantum Electronics, 2001
We analyze the properties of a distributed feedback fiber laser based on Raman amplification. Such a laser is quite practical and has a number of novel properties. We model numerically the laser dynamics, analyze in detail the role of the nonlinear refractive index of the fiber and argue on the optimal design parameters.

Picosecond distributed feedback dye lasers

IEEE Journal of Quantum Electronics, 1986
The distributed feedback dye laser is a source of single picosecond pulses tunable in a very wide wavelength range. Operational principles, experimental arrangements, and recent applications are reviewed in this paper.

Multicore fiber distributed feedback lasers

Optics Letters, 2012
We demonstrate parallel fabrication of seven fiber distributed feedback (DFB) lasers in a hexagonally arrayed multicore core Er doped fiber with 40 μm core spacing. DFB grating cavities 8 cm long and operating near 1545 nm were fabricated with a single UV inscription exposure.
