“…The fundamental peak located at the cavity repetition rate of 103 MHz has a signal-to-background ratio of 70 dB, indicating that the passively mode-locked state was stable. The narrow-band FBG (FWHM of 2 nm) also has the function of a spectral filter to balance the nonlinearity induced spectrum broadening effect [17]. Therefore, we can obtain easily stable passively mode-locked laser pulses with a high repetition rate of 103 MHz.…”

We report a stable highly-integrated high power picosecond thulium-doped all-fiber MOPA system without using conventional chirped pulse amplification technique. The master oscillator was passively mode-locked by a SESAM to generate average power of 15 mW at a fundamental repetition rate of 103 MHz in a short linear cavity, and a uniform narrow bandwidth FBG is employed to stabilize the passively mode-locked laser operation. Two-stage double-clad thulium-doped all-fiber amplifiers were used directly to boost average power to 20.7 W. The laser center wavelength was 1962.8 nm and the pulse width was 18 ps. The single pulse energy and peak-power after the amplication were 200 nJ and 11.2 kW respectively. To the best of our knowledge, this is the highest average power ever reported for a picosecond thulium-doped all-fiber MOPA system.

“…Interference between these modes causes the laser light to produce a train of pulses. Locking of mode phases enables a periodic variation in the laser output which is stable over time, and with periodicity given by the round trip time of the cavity [27][28][29][30][31][32][33].…”

“…With fixed phase relationships, the N modes can combine to interfere in such a way as to constructively interfere at multiples of the roundtrip time of the cavity, while they destructively interfere elsewhere. This process creates shorter pulses as the number of phase-locked modes increases [27][28][29][30][31][32][33].…”

The aim of this chapter is to highlight the role of simulation methods as tools for analysis of low and medium average power fiber laser operated in passively Q-switched and/or mode-locking regimes into the design of various applications such as materials microprocessing of sensor applications. The chapter's purpose consists in making available to specialists in the field of lasers, electro-optics and even nano-photonics improved procedures for designing high-accuracy remote sensors dedicated to large range of laboratory, industrial and military applications. The reason that this chapter deals with passive optical Q-switching and mode-locking techniques tailored for fiber lasers is the high percentage of sensing devices operating in this regime. Numerical simulation results obtained for this class of laser emitters can be used for other types of lasers, such as optical fiber lasers. There are briefly presented the two main mathematical methods used to analyze solid laser oscillators in passive optical Q-switching regime the coupled rate equations approach and the iterative approach. The validation of the presented numerical simulation methods is done by comparison with experimental results.

“…A conventional passively mode-locked fiber laser, which offers excellent pulse quality and transform-limited operation in a simple configuration, is an attractive approach to obtaining high fundamental repetition frequency based on a short Fabry-Perot type laser cavity [4], [5]. For self-starting modelocking, many saturable absorber (SA) materials have been developed, including semiconductor-saturable absorbers, carbon nanotubes, graphene, black phosphorus [6]- [10].…”

We demonstrate a passively mode-locked Tm-doped silica fiber laser with 535-MHz fundamental repetition rate by employing a semiconductor saturable absorber mirror. With in-band pumping at 1590 nm, the stable mode-locked fiber laser produces up to 50 mW at an incident pump power of 558 mW. The laser operating at 1938 nm has a spectral bandwidth of 0.72 nm. After amplification, the laser pulse width is measured to be ∼7.9 ps, and the time-bandwidth product is ∼0.46.Index Terms-High repetition rate, mode-locking, Tm-doped silica fiber laser.
