“…The joint development of a saturable absorber with a reflector and optimization of all laser resonator elements usually leads to the best results, as shown by the analysis of literature data and our own experience [8,9]. The authors of this article also have the experience in reaching a high lasing efficiency with a Yb:KYW laser [7,10].…”

A stable passive mode-locking regime for a Yb 3+ :KY(WO 4 ) 2 laser with optical pumping by a continuous diode laser was obtained using two types of optical shutter with a saturable absorber based on coupled GaAs/In 0.25 Ga 0.75 As/GaAs quantum wells. The shutters differed in their reflecting part: the first type was a semiconductor mirror and the second type was a dielectric one. The typical parameters of the mode-locking regime were as follows: a pulse duration of about 200 fs for both types of shutter, an average power of 2.54 W for the allsemiconductor shutter (SESAM) and 0.92 W for the dielectric mirror with a saturable absorber (DSAM). The efficiency relative to the incident pump power was 57% for the SESAM and 19% for the DSAM. The maximum pulse repetition rate was 982 MHz. The measured recovery time was about 2 ps for both saturable absorbers. The mirror damage threshold estimate for the SESAM was at least 8.87 mJ cm −2 .

“…The Yb 3+ ion has two energy levels: 2 F 5/2 and 2 F 7/2 . The two energy levels will split into multi-energy levels and the energy level spacings are different in different crystal structures [6][7][8]. Generally, the ground state, 2 F 7/2 , is split into four subenergy levels of 2 F 7/2 (0, 1, 2, 3) and the excited state, 2 F 5/2 , is split into three sub-energy levels of 2 F 5/2 (0′, 1′, 2′).…”

We present diode-pumped Yb:YVO 4 /YVO 4 thin-disk Raman laser operation around 1120 nm. The thin-disk crystals, Yb:YVO 4 , and the Raman crystal, YVO 4 , are cut with 250 μm and 20 mm, respectively. In multimode configurations, up to 0.91 W of Raman laser output power and a maximum slope efficiency of 10% are demonstrated corresponding to a pump power of 10 W. A continuous wavelength tuning range of 54 nm from 1096 to 1150 nm with a maximum output power of 320 mW at 1126 nm is confirmed.

“…The FFC consists of a femtosecond seed laser, an optical spectrum broadening system for its emission and an output frequency stabilization system. Solid-state lasers based on Ti:Sa [8,9], Cr:F [10,11] and Yb [12] crystals can be used as reference lasers. Currently, the most promising FFCs are erbium fiber lasers [13][14][15].…”

A study of the influence of temperature fluctuations of individual blocks of a fiber femtosecond frequency comb (FFC) generator and of the entire system as a whole on its output radio frequencies has been carried out. A two-circuit system for thermal stabilization of the air inside the FFC housing was implemented. An additional system for thermal stabilization of the transport fiber, which is included in the measurement scheme (outside the FFC), was implemented. A significant temperature effect on the measured output frequencies of the FFS is shown. Thanks to all the thermal stabilization systems, it has been shown that the instability of the developed fiber FFC introduced into its output microwave frequencies (in addition to the instability of the reference optical standard) is no worse than 2 × 10−16 per 1000 s.
