“…The existence of a wide application range has led to a variety of laser system configurations. They are mostly based on the principle of a master oscillator and amplifier system, where the pulses are shaped by active modulation [13][14][15]. This, on the one hand, allows flexible control of the output radiation characteristics (duration, peak power, and energy), but on the other hand, increases the complexity of the setup and introduces restrictions on the minimum pulse duration value.…”

We have demonstrated a simple all-fiber thulium (Tm) laser Q-switched by stimulated Brillouin scattering (SBS). The maximum output pulse energy was 80 μJ. This allowed us to generate a broadband spectrum directly at the laser outputs. For the first time, we measured the fine structure of the output pulses with a resolution of less than 100 ps. It was found that the SBS Q-switched laser is capable of generating bunches of picosecond pulses. The effect of modulation instability on the pulse decay is discussed. The potential application of the investigated laser radiation for producing destructive effects on soft biological tissues has been demonstrated.

A single-frequency linearly polarization pulsed fiber laser based on an electro-optic modulator with injection seeding technique is demonstrated. The single-frequency performance of the fiber ring-cavity laser is guaranteed by the seed source, which is a distributed-feedback fiber laser based on the π-phase-shifted fiber Bragg grating. The electro-optic modulator triggers active Q-switching of the laser for pulse generation. The devices used in the fiber laser are all polarization-maintaining to ensure linear polarization laser output. Through parameter optimization, the laser generates a single-frequency linearly polarization pulsed laser with a central wavelength of 1064.22 nm, linewidth of 35 MHz, and polarization extinction ratio of better than 40 dB. This type of fiber laser can be applied in lidar, beam combining, nonlinear frequency conversion, and other fields.
