“…Eye-safe 2.1 µm high-energy, injection-seeded solid-state lasers show considerable potential for radar applications, such as differential absorption radar for methane detection and coherent Doppler wind radar [1][2][3] . Because Ho:yttrium aluminum garnet (YAG) has the advantages of a long upperstate lifetime, robust mechanical properties and fascinating thermal conductivity, it is an excellent choice for emitting 2.1 µm high-energy pulses [4,5] . Considering the coherent Doppler wind radar transmitter, the single-frequency laser should have a narrow linewidth, long pulse width and high energy to ensure measurement accuracy and long-range detection.…”

“…In 2018, Wu et al [ 17 ] presented a Ho:yttrium lithium fluoride (YLF) laser with a double CCR, which achieved a 733 mW single longitudinal mode (SLM) laser output based on the Faraday effect. Immediately thereafter, Wang et al [ 5 ] used the same structure to study a Ho:YAG laser under Q- switched operation. In 2019, Wang et al [ 18 ] built a Q- switched Ho:YLF five-mirror ring laser and achieved dual-wavelength seed injection.…”

A high-energy, alignment-insensitive, injection-seeded Q-switched Ho:yttrium aluminum garnet (YAG) singlefrequency laser is developed. Both the slave Q-switched laser and the seed laser are Ho:YAG ring lasers based on a pair of corner cubic reflectors. The seed laser has an available power of 830 mW at 2096.667 nm. At 100 Hz, the Q-switched Ho:YAG laser provides a single-frequency pulsed output using injection-seeded technology. The 7.3 mJ single-frequency pulse energy from the slave laser has a pulse width of 161.2 ns and is scaled to 33.3 mJ after passing through the Ho:YAG single-pass amplifier. According to the measurement results of the heterodyne beating technique, the single-frequency pulse has a half-width of 4.12 MHz.

“…The lanthanide complexes have different applications such as light-emitting diodes (LEDs) [2][3][4], lasers [5][6][7][8], sensors [9][10][11], luminescent probes in biomedical [12][13][14][15][16], solar energy conversion [17,18], single molecule magnets [19][20][21][22][23][24], superconducting materials [25][26][27][28][29][30] etc. Ln(III) ions show distinct photophysical features, including intra-con gurational 4f-4f transitions, narrow emission bands, a signi cant Stoke's shift, a long luminescence decay time, and strong luminescence generated by electron transitions between long-time emission spectra.…”

Three new homoleptic six-coordinate Sm(III) complexes have been synthesized from diketone ligand with different substituent groups. The structural properties of these compounds have been investigated using elemental analysis, UV-Vis, and FT-IR approaches. Then, their photoluminescence properties of the synthesized Sm complexes have been examined.Also, the cytotoxic activities of the complexes have been studied against to human epidermoid carcinoma cell (HTB-54) and normal bronchus epithelial cell (BEAS-2B). According to result, the [Sm(MPBP-1,3PPon)3]·H2O) (IC50: 11.05 μM) complex was more active than [Sm(BMP-1,3PPon)3]·2H2O (IC50:58.64 μM) and [Sm(BCP-1,3PPon)3]·H2O (IC50: >500 μM) complexes. Otherwise it was no effect on normal cell (BEAS-2B). This result shows that complex [Sm(MPBP-1,3PPon)3]·H2O) has the potential to be the ideal chemotherapeutic drug.

“…Moreover, the experimentally results show that the misalignment sensitivity of the SLM ring laser could be improved by using double CCPs. In the same year, Wang et al reported a 2.09 µm Q-switched laser with two CCPs [18]. By tilting the angle of a CCP in vertical and horizontal directions to 11.8 • and 6.7 • respectively, the laser can still operate stably.…”

“…However, due to the insertion loss of the polarizer, the laser efficiency is still lower than that of ordinary resonator without CCP. Especially for 2 µm Q-switched ring CCP cavity laser usually needs two polarizers as pump injecting mirror and laser output coupler [18], and the output energy and efficiency will be limited by the low laser damage threshold of the intrcavity polarizers. Generally, the CCP can be coated with metal film to achieve the effect of polarization maintaining, which is complex process and high cost.…”

Based on the Jones matrix theory, a polarization maintaining 2 μm ring laser with a cavity structure of corner cube prisms (CCPs) is firstly presented in this paper. The changes of polarization state are simulated and coincide with the corresponding 2.06 μm experimental results for output beams after the CCP. Research results show that if the incident beam is circularly polarized or linearly polarized, the output beam will be generally elliptically polarized. Only when the polarization azimuths of linearly polarized incident beams are 16.06°, 43.94°, 46.06° and 73.94° can the linearly polarized output beams with different polarization azimuth angles be obtained. As such an incident beam passes through two CCPs arranged in the same way according to four specially reflection sequences (ACB and BCA, BCA and ACB, BAC and CAB, CAB and BAC) respectively, the polarization maintaining 2 μm laser can be realized. This work provides a reference basis for the design of a 2 μm corner cube ring cavity laser to realize the preservation of polarization state, which have practical significance to improve the output characteristics of 2 μm laser.
