A diode-end-pumped Nd：YAG dual-wavelength laser operating at 1319 and 1338 nm is demonstrated. The maximum average output power of the quasi-continuous wave linearly polarized dual-wavelength laser is obtained to be 2.1 W at a repetition rate of 50 kHz with an output power instability of less than 0.38% and beam quality factor M^2 of 1.45. Using the two lines, the highly coherent and narrow linewidth terahertz radiation of 3.23 THz can be generated in an organic 4-N, N-dimethylamino-methyl-stilbazolium tosylate （DAST） crystal. Meanwhile, the multi-wavelength red laser at 659.5, 664 and 669 nm is generated by frequency doubling and sum frequency processes in a lithium triborate （LBO） crystal. The average red laser output power is enhanced up to 1.625 W at a repetition rate of 15 kHz with an output power instability of better than 0.53% and beam quality factor M^2 of 6.05. Using the three lines, it is possible to generate the multi-wavelength THz radiation of 3.3, 3.43 and 6.73 THz in an appropriate difference frequency crystal.

Chinese Physics B 2010年第5期19卷 327-331页

A corner-pumped type is a new pumping type in the diode-pumped all-solid-state lasers, which has the advantages of high pump efficiency and favourable pump uniformity. A highly efficient corner-pumped Nd：YAG/YAG composite slab laser is demonstrated in this paper. The maximal continuous-wave output power of the 1064 nm laser is up to 18.57 W with a slope efficiency and an optical-to-optical conversion efficiency of 44.9% and 39.8%, respectively. Inserting an acousto-optic q-switch in the cavity, the highest average output power of the quasi-continuous wave 1064 nm laser of 6.73W is obtained at a repetition rate of 9.26 kHz. The experimental results show that a corner-pumped type is a kind of feasible schedules in the design of diode-pumped all-solid-state lasers with low or medium output powers.

Multiphonon-assisted acousto-optical q-switched laser at 1130 nm in Yb:YCOB crystal

Chinese optics Letters 2024年第10期22卷 70-74页

In this Letter,we realized the phonon-assisted q-switched laser operation in Yb:YCOB *** from previous laser wavelengths below 1.1μm,we extended the wavelength to 1130 nm by amplifying multiphonon-assisted electronic *** a repetition rate of 0.1 k Hz,the laser output power was 82 m W with a pulse width of 466.1 ns,corresponding to a high peak power of 1.76 k W and a single pulse energy of 0.82 m J,*** the best of our knowledge,this represents the highest pulse energy among all Yb^(3+)-doped crystal lasers at the wavelength beyond 1.1μ*** a large pulse energy could be explained by the laser rate-equation *** results indicated that the electron-phonon coupling effect not only extends the lasing wavelengths but also enables a fast temporal response to support nanosecond,picosecond,even femtosecond pulse laser operation.
