摘要：
In order to expand the available bandwidth for wavelength division multiplexing transmission systems, a 1.65 mum-band optical fibre amplifier with Er3+-doped fluorozirconate fibre using 0.8 mum upconversion pumping has been demonstrated. The positive gain, 3.8 dB, is the first ever achieved by means of (H-2(11/2), S-4(3/2)) --> I-4(9/2) stimulated emission transition.
