We demonstrate, for the first time to the best of our knowledge, a highly efficient continuous-wave two-pump fiber optical parametric amplifier. We used a total pump power of /spl sim/280mW in a 14-km-long fiber and obtained 88% power transfer from pumps to signal and idler over 25-nm bandwidth centered at 1568 nm.
