“…However, several applications such as interferometric gravitational-wave detection [58], coherent Light Detection and Ranging (LIDAR) [59], laser nonlinear frequency conversion [60], coherent beam combining [61] and laser spectroscopy [62] require laser emissions with narrower linewidth. This feature can be provided by single-frequency fiber lasers, which are lasers that operate with only a single-longitudinal mode and thus can emit quasi-monochromatic radiation with a very narrow linewidth and low noise.…”

Abstract:In recent years, the exploitation of compact laser sources and amplifiers in fiber form has found extensive applications in industrial and scientific fields. The fiber format offers compactness, high beam quality through single-mode regime and excellent heat dissipation, thus leading to high laser reliability and long-term stability. The realization of devices based on this technology requires an active medium with high optical gain over a short length to increase efficiency while mitigating nonlinear optical effects. Multicomponent phosphate glasses meet these requirements thanks to the high solubility of rare-earth ions in their glass matrix, alongside with high emission cross-sections, chemical stability and high optical damage threshold. In this paper, we review recent advances in the field thanks to the combination of highly-doped phosphate glasses and innovative fiber drawing techniques. We also present the main performance achievements and outlook both in continuous wave (CW) and pulsed mode regimes.Keywords: fiber laser and amplifier; phosphate fiber; all-fiber master oscillator power amplifier (MOPA); rare-earth-doped fiber

“…One can see the whole MOPA-based pulsed fiber laser system is all fiber-based monolithic. For the longer ns transform-limited pulses, the main limit for the energy or power scaling is the stimulated Brillouin scattering (SBS) in the fiber amplifiers [6][7][8][9][10]. Therefore, we used the newly developed larger core SM PM highly Tm-doped (4%) germanate fiber LC-TGF 25/250 in the power amplifier stage shown in Fig.…”

“…These Q-switched fiber laser pulses have been successfully used in nonlinear frequency conversion and laser remote sensing [9][10]. In this method, a piezoelectric compresses a fiber creating stress birefringence, and this birefringence acts as a waveplate, changing the polarization state of the light in the fiber.…”

We report an all fiber-based single-frequency Q-switched 2 μm pulsed laser based on highly Tm-doped germanate fiber by using a piezo to induce stress in fiber laser cavity. The pulse width of this Q-switched fiber laser can be tuned from 10's ns to sub-μs. The repetition rate can be tuned from 100 Hz to 100's kHz. The average power is ~ mW-level, peak power wattlevel, and pulse energy 30-75 nJ without any amplifier. Moreover, this transform-limited fiber laser pulses has been scaled up to 220 μJ by using a newly developed SM PM highly Tm-doped germanate fiber 25/250μm for transform-limited 80 ns pulses at repetition rate 20 kHz. This narrow linewidth high energy MOPA-based pulsed fiber laser can be used for LIDAR and laser remote sensing.

“…1 shows the schematic of the monolithic pulsed fiber laser in MOPA, which has been designed and implemented for high power/energy with long pulse duration (> 100ns) and narrow linewidth. One can see that the pulse seed is a Qswitched fiber laser seed at 1530 nm, which we have developed recently [9][10][11][12][13]. Using one piece of piezo material we can control the Q-switching performance.…”

We report a monolithic high SBS-threshold pulsed fiber laser in MOPA for longer nanosecond pulses with transformlimited linewidth. By using a single mode polarization-maintaining large core 25 μm highly Er/Yb co-doped phosphate fiber in the power amplifier stage, we have achieved the highest peak power of 1.2 kW at 1530 nm for 105 ns pulses with transform-limited linewidth, and with a corresponding pulse energy of about 0.126 mJ. The achieved high-energy pulses were frequency doubled by using a commercial periodically poled lithium niobate (PPLN) crystal, and the highest SHG peak power of 271 W has been achieved for the SHG pulses at 765 nm.
