“…The fifth harmonic of 1074, 214.8 nm, can be used to detect nitric oxide (NO), because the 214.8 nm lies in the absorption band of NO [2]. 1074 nm laser can also be used as a pump source for superfluid 4 He [3]. However, it is difficult to obtain an oscillation of 1074 nm, because it is close to the stronger emissions around 1064 nm and is usually suppressed.…”

“…Several ways have been reported for realizing oscillation around 1074 nm [2,[4][5][6][7]. In order to restrain the stronger transitions near 1064 nm and realize an oscillation around 1074 nm, specially coated mirrors are usually exploited [2,4]. Sometimes an etalon is used alone [5,6] or together with the specially coated mirrors [7] to realize an oscillation around 1074 nm.…”

We designed and fabricated a dielectric Fabry-Perot filter (FPF) with pass band of 24 nm as the output coupler of a [111]-cut Nd:YAG laser to restrain the strong emission near 1064 nm and obtain a 1073.8 nm lasing output with a planoplane resonator cavity. The threshold pump power is about 2.9 W. The maximum output power is 261.7 mW at pump power of 5.3 W and the slope efficiency is 12.1 %. Passively Q-switched 1073.8 nm laser is realized using a [100]-cut Cr:YAG crystal as the saturable absorber. The full width at half maximum (FWHM) pulse duration of 75.7 ns and pulse repetition rate of 4.23 kHz is achieved at pump power of 5.3 W. The design principle of the Fabry-Perot filter used as output mirror is discussed and the advantages of the method are summarized.

“…This kind of laser resources can be efficiently obtained by actively or passively Qswitching and mode-locking in solid-state lasers [6][7][8][9][10]. For high peak power applications, passively Q-switched and mode-locked lasers are more desirable than actively ones because of their compactness and simplicity.…”

“…The laser is optically pumped with flash-lamps [7]. The quadratic KTiOPO 4 (KTP) crystal, which acts as saturable absorber, exploits the existence and properties of non diffractive spatial three wave solitons [19][20][21], in par- x, a.u.…”

We report experimental results on the mode-locked operation of a flash-lamp-pumped Nd:YAG laser at 1.064 μm. The KTP crystal, which induces passive mode-locking, exploits the existence and properties of spatial Zakharov-Manakov soliton dynamics. A train of pulses with duration close to 100 ps, repetition rate of 136 MHz and modulation depth almost 100% has been produced. The mode-locked pulses are modulated with a longer 180 ns pulse envelope with repetition rate of 10 Hz. ns 100 psOscilloscope trace of a train of mode-locked 100 ps pulses of the flash-pumped Nd:YAG at 1.064 μm.

A corner-pumped Nd:YAG/YAG composite slab continuous-wave laser operating at 1064 nm, 1074 nm, 1112 nm, 1116 nm, and 1123 nm simultaneously and a laser that is tunable at these wavelengths are reported for the first time. The maximum output power of the five-wavelength laser is 5.66 W with an optical-to-optical conversion efficiency of 11.3%. After a birefringent filter is inserted in the cavity, the five wavelengths can be separated successfully by rotating the filter. The maximum output powers of the 1064 nm, 1074 nm, 1112 nm, 1116 nm, and 1123 nm lasers are 1.51 W, 1.3 W, 1.27 W, 0.86 W, and 0.72 W, respectively.
