Boosting Output Power of Multiwavelength Fiber Laser with Lyot Filter utilizing Hybrid Amplifier
This paper presented an investigation on the effect of hybrid amplifier to multiwavelength fiber laser (MWFL) with in-cavity Lyot filter. The hybrid amplifier comprising semiconductor optical amplifier (SOA) and erbium doped fiber amplifier (EDFA) was used to boost the lasing output peak power. The multiwavelength lasing output has improved by 20 dB, while the extinction ratio (ER) increased to 4 dB when hybrid amplifier was used. The lasing lines remain stable, with a maximum 2.94 dB of power dithering within 100 minutes of observation.
