光纤激光器
摘要：
本发明披露了一种光纤激光器，该光纤激光器包括单模或低阶模包层泵浦光纤激光振荡器或前置放大器(1)，适合于导引多横模的包层泵浦光纤激光功率放大器(2)，其中，来自振荡器或前置放大器的输出通过模混合装置(3，4)而施加至功率放大器。与振荡器或前置放大器相比，激光功率放大器具有较大的纤芯和包层直径，因而使得可以应用较低亮度的泵浦源。
摘要（英）：

The present invention discloses a fibre laser comprising a single mode or low-order-mode cladding pumped fibre laser oscillator or preamplifier, a cladding pumped fibre laser power amplifier adapted to guide multiple transverse modes, wherein an output from the oscillator or preamplifier is applied through a mode mixing means to the power amplifier. The laser power amplifier is of greater core and cladding diameter than the oscillator or preamplifier, thus enabling lower brightness pump sources to be employed.
