Low Noise High Power Ultra-Stable SS Laser for 1550nm Wavelength Band

Abstract

The authors have developed a tunable laser technology based on optical pumping of Yb and Er doped high phosphate glass (Laporta, 2001). Er doped glass is widely used for fiber amplifiers in the 1550nm wavelengths. High phosphate glass permits very high doping of Yb and Er so that small cavity length solid-state lasers can be built. Methods for tuning these lasers include rotating glass etalon and tunable Bragg fiber. We have developed a tunable laser using piezoelectric moveable mirror for mode selection and cavity tuning. The properties of these lasers are high SMSR and low RIN
