We present a high power red green blue (RGB) laser light source based on cascaded quasi phase matched wavelength conversions in a single stoichiometric lithium tantalate. The superiority of the experi mental setup is: the facula of the incident beam is elliptical to increase interaction volume, and the cavity was an idler resonant configuration for realizing more efficient red and blue light output. An average power of 2 W of quasi white light was obtained by proper combination of the RGB three colors. The conversion efficiency for the power of the quasi white light over pump power reached 36%. This efficiency and powerful RGB laser light source has potential applications in laser based projection display et al.

“…However, only a few publications have described parametric superluminescence in a periodically poled lithium niobate (PPLN) structure. These publications [4,5] studied the superluminescence of this type of crystal with pumping by short pulses (duration ~1 ns) using a Nd:YAG-microchip-laser; the total efficiency of the conversion of the pump wave into a signal wave and idler was 25%-30%. In Galvanauskas et al [6], the pumping of a PPLN structure was performed with second harmonics of 777 nm using an Er-doped fiber МОРА system, and in Sudmeyer et al [7] a disk Yb:YAG-laser was used.…”

We present results on parametric superluminescence in a periodically poled lithium niobate crystal pumped by a train of 45 ps pulses using a Q-switched mode locked Nd:YAG laser. The conversion efficiency (with respect to the absorbed power) was ~83%. To the best of our knowledge, this is the highest efficiency obtained with powerful superluminescent parametric sources. At the average pumping power of the laser of ~0.5 W and repetition rates of 1 and 1.7 kHz, the peak total output powers were as high as 210 and 200 kW, and the powers of the idler wavelength (3.82 µm) were 55 and 50 kW. New lines in the visible and UV spectrum were observed and are explained. The experiments demonstrated that the spectral and angular characteristics of superluminescence are determined by the pumping laser. In particular, the line width of the signal wave was close to that of the pumping line at ~200 GHz, and the divergence of the signal and idler waves depended only on the convergence (divergence) angle of the pumping radiation (30 mrad) and was independent of the wavelength.

“…Several laser sources, such as lead-salt diode laser, quantum cascade laser [3], colorcenter laser, Raman lasers [4,5] and optical parametric oscillator (OPO) [6,7], can emit CW laser radiations in the mid-infrared region. However, all these sources have their own issues when they are put into practical applications.…”

“…Widely tunable continuous-wave (CW) middle infrared (mid-IR) laser sources are very useful for applications in trace-gas detections, medical diagnosis, biological and chemical analysis because the fundamental rotation and vibration lines for many gas molecules are located in the mid-IR region where the absorptions are stronger than those of their overtones in the near-infrared region by 2-3 orders of magnitude [1,2]. Several laser sources, such as lead-salt diode laser, quantum cascade laser [3], colorcenter laser, Raman lasers [4,5] and optical parametric oscillator (OPO) [6,7], can emit CW laser radiations in the mid-infrared region. However, all these sources have their own issues when they are put into practical applications.…”

Abstract:In this paper we report a fiber-type widely tunable CW mid-IR DFG/QPM laser source based on periodically poled MgO-doped LiNbO 3 (PPMgLN), which uses a ytterbium-dope fiber laser (YDFL) as the pump source and a tunable erbium-dope fiber laser (EDFL) cascaded with an erbium-doped fiber amplifier (EDFA) as the signal source. Our experimental results show that, with the PCs to adjust the pump and signal polarization orientations being parallel to the crystal principle optical axis the conversion efficiency may be optimized. The pump and signal beam spots and their longitudinal evolution behaviors determine the RCE and the crystal longitudinal position tolerance, which are measured to be 0.717 (mW) −2 and 44 mm for the mid-IR laser source, respectively. The idler output of the mid-IR DFG/QPM laser source may be continuously tuned from 3.1 to 3.6 μm with almost the same RCE.Idler output
