Paper Abstract

Strong pump absorption in Er/Yb codoped fiber grating lasers was found to cause large optical frequency fluctuation besides lasing wavelength shift. The temperature rise due to the pump induced heating within the Er/Yb fiber cavity was theoretically investigated, which caused the lasing wavelength shift with the increase of 980 nm pump power. An experimental setup was also built to estimate the optical frequency fluctuation under a fixed pump power. The observed 1.7 GHz optical frequency fluctuation was reduced to less than 90 MHz through proper thermal dissipation.
