“…Then Sidorenko et al successfully used the GMN amplifier-based laser source in the multi-photon microscopy and scaled the pulse energies to µJ level by using largemode-area fiber amplifiers [3,16]. Some researchers also followed and researched characteristics of the GMN amplifier including the impact of pump configuration [17], seed temporal, spectral shapes, repetition rate, and pulse energy on the GMN amplification [18]. Look at a lot of previous research on sub-100 fs laser pulses generation, not a few of them actually work on the GMN regime [6,7,12,19].…”

We demonstrate an all-fiber monolithic laser source from a gain-managed nonlinear (GMN) fiber amplifier with a CFBG-based pre-compressor that generates high-contrast pulses with a repetition rate of 80 MHz, average power of 1.6 W, and pulse duration of sub-50 fs. The compressed pulse quality can be optimized by tuning the parameters of the seed pulses injected into the GMN amplifier by controlling the pump power of the fiber pre-amplifier. This compact and cost-effective laser system is a simplified design of the GMN amplification-based femtosecond fiber laser systems. With alignment-free characteristics in the amplifiers and clean compressed pulses, it is easy to assemble and use in applications such as multi-photon microscopy.
