净增益 meaning in English
net gain
Examples
- 3 . 5 cm long and 4um wide channel silica glass waveguide was fabricated by ag + - na + ion - exchange and 5 db net gain at 1536 nm was obtained with a pump power of 250 mw ( at 980 wavelength ) ; fwhm is 14 nm around 1536 nm
用波长为980nm ， 250mw的半导体激光器泵浦该条型波导，在1536nm波长下得到的最大净增益是5db ：在1536nm附近3db净增益谱带宽是14nm 。
