Abstract

A narrow linewidth injection-seeded Q-switched fiber ring laser based on a low-SBS optical fiber. High peak powers are achieved through the use of a single-clad erbium doped fiber with an acoustic waveguide. 12.5 μJ per pulse (250 ns pulse width) is achieved before a weakened form of stimulated Brillouin scattering appears. This laser has the potential to scale to very high power in a low-SBS dual clad fiber.

Claims

exact text as granted — not AI-modified
1 . A narrow-linewidth injection seeded Q-switched fiber ring laser comprising;
 a low-SBS Er doped fiber.   
   
   
       2 . The laser of  claim 1  wherein the laser provides 12.5 μJ per pulse (250 ns pulse width). 
   
   
       3 . The laser of  claim 1  wherein the laser is utilized as a saturating master oscillator for a high power low-SBS dual-clad fiber amplifier or stand-alone transmitter for micropulse lidar applications.
