“…The corresponding concentration variation of HF 0 inside the HF laser cavity is presented in figure 2. Figure 2(a) provides the calculated HF 0 concentration with and without gas replenishment, while figure 2(b) illustrates the measured HF 0 concentration by the tunable diode laser absorption spectroscopy technique [33,34] when the pulsed HF laser is operated without scrubbing or gas replenishment. As can be seen in figure 2(a), the concentration of the HF 0 molecule accumulates linearly with the pulse number.…”

Pulse energy sustainability of a burst mode closed-cycle pulsed HF laser is investigated with a simple theoretical model considering gas replenishment and chemical scrubbing. The effects of reactant gas consumption and de-excitation of excited HF by ground state HF are studied quantitatively. Also, experiments are carried out for comparison and validation. Simulation and experiments show that, in the burst mode operation, the energy loss caused by gas consumption is about 0.06-0.12 mJ per pulse while that induced by the de-excitation process is about 0.22-0.29 mJ per pulse, demonstrating that chemical scrubbing should play a more important role in the energy preservation of non-chain pulsed HF lasers.

In this paper, a high power Tm 3+ -doped fiber laser (TDFL) based on a monolithic master oscillator power amplifier (MOPA) system with the center wavelength is 1940 nm is demonstrated. The maximum laser power was measured to be 200 W with a slope efficiency of 56.2% at the 793 nm pump power of 368.6 W. Power stability of the laser output over 60 min is measured to be ~0.12%, which indicate a relatively stable laser operation of the TDFL. The output power is limited by the available pump power for the lack of amplified spontaneous emission, parasitic oscillation or self-pulsing effects even at the maximum output power level, showing further power scaling should be possible with increase the pump power.

“…Multi-wavelength fiber lasers (MWFL) are attracting increased research attention because of their simple structure, good heat dissipation, portability, and high efficiency [1][2][3]. Because of their potential to broaden the channel capacity of communication systems, the development of multi-wavelength lasers near the 2-μm waveband has attracted particular research attention [4][5][6].…”

A switchable multi-wavelength thulium-doped fiber laser (TDFL) using either two-stage cascaded or two-segment Sagnac loop filters are proposed and analyzed. Both filters incorporate a 3-m and 1.7-m long polarization-maintaining fiber, which acts as a comb filter. By adjusting two polarization controllers, when the TDFL used a cascaded Sagnac loop filter, eight stable single-wavelength operations were obtained with easy switching among them. The wavelength range was 16.36 nm during the singlewavelength switchable operation, with the optical signal-to-noise ratio up to 55 dB. This TDFL can achieve at most quintuple-wavelength operation. When the TDFL used a two-segment Sagnac loop filter, we achieved single-wavelength and dual-wavelength switchable. This TDFL can achieve at most stable quadruple-wavelength operation. In dual-wavelength switchable operation, the maximum and minimum wavelength spacings were 21.78 nm and 1.50 nm. Due to its abundant range of wavelengths, the proposed TDFLs has great potential in wavelength-division multiplexing.INDEX TERMS Multi-wavelength thulium-doped fiber laser, wavelength switchable, cascaded Sagnac loop filter, two-segment Sagnac loop filter.
