“…From 2008 B.Q.Yao has reported several Ho:YAP pumped by 1.91μm Tm:YLF laser, 1.91μm, 1.936μm and 1.948μm Tm:doped fiber laser. The reported highest power is 14.6W corresponding to 69.35% slope efficiency at continuous wave pumped by Tm:YLF laser, and when it was pumped by Tm:fiber laser, 11W output power was obtained corresponding to 62.1% slope efficiency [8][9][10][11].…”

We report on the continuous wave operation of a Ho:YAP laser pumped by an all-fiber Tm-doped fiber laser, the pump laser wavelength is 1.915μm and the output laser wavelength is 2.118μm. The all fiber Tm-doped fiber laser has 70W max output power with 200W pumped power, and the output laser wavelength is 1.915μm. And this laser is used as pump laser to a Ho:YAP laser system. 20.2W CW laser power is obtained from a 0.5 at % Ho 3+ -doped YAP crystal at 2118.4nm with slope efficiency of 72%.

“…In the case of holmium-doped materials, mainly YAG and YLF crystals were investigated thoroughly and found suitable for efficient and usually tunable laser generation around 2.1 µ m [15,16] as well as for picosecond pulses amplification in this spectral region [17,18]. Laser operation of some other holmium-doped active materials as YAP, LLF, LuAG, and GdVO 4 was also demonstrated [15,[19][20][21]. On the other hand, only a few works is devoted to the laser operation of holmiumdoped fluorides as CaF 2 .…”

The laser operation in the pulsed as well as continuous-wave regime of a modified-Bridgeman-grown 0.5 at.% Ho:CaF2 crystal at 83 K pumped by a Tm:fiber laser is reported. The maximum output power was 2.37 W at 2060 nm or 1.3 W at 2110 and 2130 nm. Continuous tuning range over 90 nm from 2030 to 2120 nm was achieved using a birefringent filter. The Ho:CaF2 fundamental spectroscopic properties as absorption and fluorescence spectra at 83 and 293 K are also presented.

“…In recent years, high efficiency Ho oscillators in different configurations based on several hosts as YAG [16,17], YLF [18,19], YAP [20], LuAG [21], LLF [22], LSO [23], ceramic [24], and silica fiber [25,26] have been developed and reported. If we are talking about Ho:YAG lasers, it seems that diode-pumped Tm-doped bulk lasers [27,28] and Tm-doped fiber lasers [29] seem to be the most attractive sources for direct pumping.…”

We describe an efficient, low-threshold, continuous-wave (CW) and Q-switched operation of a Ho:YAG laser resonantly, single-pass pumped by a 20 W linearly polarized narrow line width Tm: fiber laser at the wavelength of 1,908 nm. At room temperature for an output coupler of 30 % transmission, a maximum continuous-wave output power of 13.3 W for 18.9 W of absorbed pump power was achieved, corresponding to a slope efficiency of 73 %. In a quasi continuous-wave pumping regime, for several output couplers slope efficiencies of almost 82 % were observed. For a Q-switched operation, a Brewster-cut acousto-optic modulator was used. In a CW pumping regime, the pulse repetition frequency (PRF) was changed from 4 to 15 kHz. Under a Q-switched operation, the maximum output power of 12.25 W in relation to 15 kHz PRF was obtained; however, the maximum peak power of almost 250 kW at the PRF of 4 kHz was demonstrated. In the best case, for 4 kHz PRF, pulse energies of 2.18 mJ with a 8.8 ns FWHM pulse width (one of the shortest pulse durations observed in holmium-doped Q-switched lasers) were achieved. The laser operated at the wavelength of 2,090.23 nm with the FWHM line width of 0.95 nm. The beam quality factor of M 2 was measured to be below 1.42 in both X and Y axis.
