5 parameters of an optical amplifier
The optimal parameters are 4 degrees of noncollinearity, β-barium borate (BBO) as the material, a 400-nm pump wavelength, and signal around 800 nm (and can be tunable in the range 605-750 nm with sub-10 fs pulse width which allows exploring the ultrafast dynamics of large molecules. It is essentially the same as an optical parametric oscillator, but without the optical cavity (i. E ( t ) + n ( t ) Booster (power) amplifiers: Boost power into transmission fiber, low NF, high Psat. 1- The signal is amplified with gain as in the following equation: ( d I[z ])/(d z) =g I but gain g can be saturated: g= g0/(1+ I(z) /Isat) where g0 is a characteristic value, and Isat, the saturation intensity is: Isat = ( spont/(2 stim)) h n where spont and stim are the. The amplification factor or gain can be higher than 1, 00 (> 30 dB) in some devices.
