Gain narrowing effect
WebOct 27, 2024 · Therefore, only the gain narrowing effect contributed to the spectral modulation in the subsequent fiber amplifiers. The average powers of the amplified signal pulses delivered by the subsequent fiber amplifiers were optimized to be 102.1 mW, 1.55 W, and 10.21 W, respectively. The spectral bandwidth was further decreased from 9.6 nm to … WebApr 21, 2024 · The gain narrowing issue is caused by the narrow and uneven emission spectrum of the Yb:YAG crystal. Explicitly, the emission spectrum width is less than 8 nm at the cooling temperature of 20 °C, moreover, the central wavelength component has a higher gain than the off-center wavelengths.
