All-Fiber Configuration Laser Self-Mixing Doppler Velocimeter Based on Distributed Feedback Fiber Laser
In this paper, a novel velocimeter based on laser self-mixing Doppler technology has been developed for speed measurement. The laser employed in our experiment is a distributed feedback (DFB) fiber laser, which is an all-fiber structure using only one Fiber Bragg Grating to realize optical feedback and wavelength selection. Self-mixing interference for optical velocity sensing is experimentally...
متن کاملAll-Fiber Bismuth Doped Self-Sweeping Laser
Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...
متن کاملMultiwavelength generation in a random distributed feedback fiber laser using an all fiber Lyot filter.
Multiwavelength lasing in the random distributed feedback fiber laser is demonstrated by employing an all fiber Lyot filter. Stable multiwavelength generation is obtained, with each line exhibiting sub-nanometer line-widths. A flat power distribution over multiple lines is obtained, which indicates that the power between lines is redistributed in nonlinear mixing processes. The multiwavelength ...
متن کاملfrequency all - fiber laser in master oscillator power amplification configuration
We present a high power, single-frequency fiber amplifier based on master oscillator power amplification (MOPA) chains in all-fiber configuration. A 1.5 meter long highly doped Yb fiber with absorption coefficient as high as 16 dB/m at the 975 nm wavelength is used for the main power amplifier, no special assistant stimulated Brillouin scattering (SBS) suppression approach is employed. The maxi...
