A wavelength switchable ring cavity thulium-doped fiber laser (TDFL) based on Mach-Zehnder interferometer (MZI) is designed. The MZI is fabricated by cascading single-mode and coreless fibers, and the proposed TDFL can generate single-, double-, and triple-wavelength laser emission. The single-wavelength laser tuning scope is 39.2 nm from 1896.1 to 1935.3 nm, and its power fluctuation is less than 0.665 dB. In the experiment, three different groups double-wavelength and two different groups triple-wavelength lasers can be generated through adjusting PC respectively. For the designed fiber laser, the signal to noise ratio is more than 30 dB.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
