Rofin FL series has excellent beam quality and can be coupled in fiber optics
with diameters of 50 μm up to 600 μm. This is equivalent to beam qualities of 2.5 to 30 mm x mrad. The ROFIN FL 010 S optionally offers a fiber laser solution with single
mode beam qualities of typically 0.4 mm x mrad and 1,000 Watt output powers.
这里,beam qualities of 2.5 to 30 mm x mrad是指的什么呀?光斑束腰半径和发散角的乘积吗?范围从2.5到30,跨度有这么大吗?下面还有0.4 mm x mrad ,哪位好心的大侠能给解释一下? |
