Both methods have a high pump efficiency, pump with 10mw power, you can get 30 ~ 40db of gain.

Both pump efficiency is very high, with a pump power of 10mW, could gain 30~40dB gain.

These two way pump efficiency very is all high, with the 10mW pump power, can obtain 30~40dB the gain.

These two modes of pump efficiency are very high, 10 mW used the pump power, we will be able to achieve 30 ~ 40 dB gains.
