“…What is more, Q-switched lasers can also be used for measurement purposes, such as for distance measurements by measuring the time it takes for the pulse to get to some target and the reflected light to get back to the sender. So far, it is possible to get the tunable Q laser pulse from various lasers with the single pulse energy and the peak power being µJ and kW order of magnitude, respectively [1]. However, in the application of the spectral analysis of the interaction between light and matter, and the precision measurement of the sensing detection based on the coherence principle, we need to find the Q-switched laser pulse with a single-longitudinal mode and narrow linewidth [2].…”

The self Q-switched characteristic of the single longitudinal-mode distributed Bragg reflector (DBR) erbium-doped fiber laser (EDFL) with narrow linewidth pulse output is demonstrated without any extra saturable absorber or electro-optic and acoustic-optic modulator, and it is provided with a simpler structure and lower cost. The proposed pulse laser operates at approximately 1550.33 nm with a 20 dB bandwidth of 0.56 nm and signal-to-noise ratio of about 55 dB. By increasing the 980 nm pump power from 80-330 mW, the repetition rate of the output pulse increases from 73.53-147.1 kHz while the pulse width decreases from 1.4-0.2 µs, which shows the feature of the narrow linewidth ideally. The maximum pulse energy of 0.379 nJ and peak power of 1897.2 µW are generated with a repetition rate and pulse width of 147.1 kHz and 0.2 µs, respectively. The result shows that the self Q-switched pulse of the DBR EDFL is obviously dependent on the applied pump power and possesses the characteristic of the single longitudinal mode and the narrow linewidth, offering potential utilization in industrial processing and scientific research.

“…In recent years, Yb 3+ ions doped gain materials have attracted much attention for their application to the compact high power and high efficiency lasers, such as Yb:YAG and Yb:LuAG materials, because of their simple electronic energy level schemes ( 2 F 5/2 -2 F 7/2 intermanifold transition) [3][4][5][6][7][8][9][10][11][12][13][14][15]. Yb:YAG crystals or polycrystalline ceramics are regarded as one of the dominant laser gain mediums due to their excellent properties in optical, chemical, thermal and mechanical aspects [16,17].…”

An intracavity cascaded Raman laser with the Stokes and anti-Stokes emissions from a single KTiOPO4 crystal pumped by a passively Q-switched Yb:YAG laser near 1050 nm was demonstrated. A total conversion output power of 666 mW was obtained at a repetition rate of 9.8 kHz with an overall conversion efficiency of ∼3%. The shortest pulse duration of the third Stokes radiation near 1148 nm was measured to be 764 ps, giving out a pulse energy of 13 µJ and peak power of 17.1 kW. Meanwhile, pulse duration of 1.54 ns at anti-Stokes line was also obtained with a peak power of 3.5 kW. The effective Raman gain was estimated to be ∼2.1 cm/GW.
