English abstract The present manuscript shows linear cavity fiber laser experimental analysis. The fiber laser arrangement, uses an all fiber mechanical long period grating (MLPG) to control single and dual laser emission. Here, single laser emission centered at 1562 nm with a signal to noise ratio of 27 dB and a linewidth less than 0.1 nm is obtained and tuned from 1562 nm to 1546 nm, by twisting a conventional section of single mode fiber that was set into the MLPG. Thus, when the twist is around 120∘ dual emission is obtained with centered wavelengths at 1533 nm and 1546 nm, these emissions can be switched between them when the twist is incremented and the peak centered at 1546 nm is tuned in backward direction. The proposed laser offers wavelength and power stability with minimal variations of 0.5 dB and 0.5 nm respectively. This laser can be applied in several fields such as sensing, optical signal analysis and, optical communications
