Laser exhibition technology has been widely used in the virtual environment of exhibitions and shows, as well as in the physical conference and exhibition centers. However, the speckle issue due to the high coherence of laser sources has caused harmful impacts on image quality, which is one of the obstacles to exhibition effects. In this paper, we design a compact Nd:YAG/PPMgLN laser module at 561.5 nm and use two different types of big-core multi-mode fibers to lower the spatial coherence. According to our experiment, the speckle contrasts relating to these two types reduce to 7.9% and 4.1%, respectively. The results of this paper contribute to improving the application effects of key optical components in the exhibitions. Only in this way can we provide technical supports and service guarantee for the development of the exhibition activities, and an immersive interactive experience for the audiences.

“…Therefore, a lot of research has been done on whether the inner cavity structure or the extra cavity structure to choose pulse pumping or continuous pumping. [14][15][16][17][18][19][20][21] Compared with PPLN, PPLT has a stronger photorefractive resistance threshold and a greater potential in the field of laser emitting in the near and mid-infrared spectral regions. [22][23][24] In 2011, Wei Xingbin and others of the Institute of Applied Electronics, Chinese Academy of Engineering Physics used a 1064 nm Nd:YAG laser with a repetition frequency of 5 kHz to pump PPLT crystals, with the signal singly resonant oscillator (SSRO) and idler singly resonant oscillator (ISRO) design and obtained 5.78 W and 5.07 W 3.9 μm mid-infrared output.…”

A high power, high-conversion-efficiency, and tunable continuous-wave external cavity pump singly resonant optical parametric oscillator (OPO) was proposed in this article. This OPO was based on multi-grating MgO-doped stoichiometric periodically poled LiTaO 3 (MgO:sPPLT) and pumped with 532 nm continuous wave fiber laser. The MgO:sPPLT-OPO could provide near-infrared radiation across 821-879 nm in the signal and 1352-1515 nm in the idler within four grating periods of 8.3-8.6 μm. When the pump power was 5.4 W, the maximum pump-to-signal conversion efficiency could reach 57.5% at 821 nm. The output power extended to 5.9 W in each period when the pump power reaches 13.6 W.

“…In particular, CW-OPOs become widespread for application, since periodically poled ferroelectric crystals are introduced to realize quasi-phase-matching (QPM) [2,3]. CW-OPOs based on various periodically poled materials such as PPLN, PPLT, PPKTP, and PPRTA have been reported in the literature [4][5][6].…”
