A simple technique for achieving a stable, room temperature and multi-wavelength lasing with narrow linewidth is demonstrated using Brillouin ber laser （BFL） with a 100-m-long photonic crystal ber （PCF） in conjunction with a dual-pass configuration. A broadband ber Bragg grating （FBG） operating in the C-band region is incorporated at the end side of the setup to allow a dual-pass operation. The proposed BFL can operate at any wavelength depending on the Brillouin pump wavelength and the FBG＇s reflection region used. With a Brillouin pump （BP） of 15.7 dBm, approximately 7 stokes and 4 anti-stokes lines are obtained with a line spacing of 0.08 nm.

An analys.s is performed for the hydromagnetic second grade fluid flow between two horizontal plates in a rotating s.stem in the presence of a magnetic field. The lower sheet is considered to be a stretching sheet, and the upper sheet is a porous.solid plate. By suitable transformations, the equations of conservation of mass and momentum are reduced to a s.stem of coupled non-linear ordinary differential equations. A series of solutions to this coupled non-linear s.stem are obtained by a powerful analytic technique, i.e., the homotopy analys.s method （HAM）. The results are presented with graphs. The effects of non-dimensional parameters R, A, M2, a, and K2 on the velocity field are discussed in detail.
