摘要	A tunable external cavity laser for use as a pump laser in an optical amplifier such as a Raman amplifier or erbium doped fibre amplifier comprising a semiconductor gain device (12) operable to provide light amplification, a diffraction grating (18) for selecting the wavelength of operation of the laser and a MEMs actuator for changing the selected wavelength. A plurality of gain devices can be coupled together to improve the bandwidth or gain of the optical amplifier.
其他摘要	一种可调谐外腔激光器，用作光学放大器中的泵浦激光器，例如拉曼放大器或掺铒光纤放大器，包括可操作以提供光放大的半导体增益装置（12），用于选择波长的衍射光栅（18）激光器的操作和用于改变所选波长的MEMs致动器。多个增益装置可以耦合在一起以改善光放大器的带宽或增益。
主权项	1 . A tunable light source for use in an optical amplifier, comprising: a gain device operable to provide light amplification, the gain device comprising a gain medium and a first reflective surface; a wavelength selector which selects a part of the light from the gain device; and an output coupler; wherein the output coupler directs a portion of the light from the gain device towards the wavelength selector and another portion into an optical propagator for coupling to an optical amplifier, such that the gain device, output coupler and wavelength selector form a resonator.
