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.

“…Recently, in order to satisfy the demands of multiple species or multiple absorption lines synchronous detections, much research has been focusing on enlarging the DFG tuning range. However, in most cases, the poling period or the crystal temperature should be adjusted frequently during the wavelength tuning process, due to restrictions imposed by the quasi phase matching (QPM) wavelength acceptance bandwidth (BW) [9][10][11][12]. It will inevitably cause much inconvenience for the practical application.…”

In this paper, the wide difference frequency generation (DFG) tuning characteristics around 3.4 μm are investigated by using the index dispersion property of PPLN. With a ytterbium doped fiber laser (YDFL) and an erbium doped fiber laser (EDFL) as the fundamental light sources, our simulation results show that the quasi phase matching (QPM) wavelength acceptance bandwidth (BW) for the pump is much larger than that for the signal. Although the positions of the broadened QPM pump bands vary with the poling period and the signal wavelength, the corresponding idler tuning ranges center around 3.4 μm. With a signal wavelength of 1.57 μm, an idler tuning range of greater than 170 nm is experimentally obtained in the 30 uni form grating PPLN. When the signal wavelength and the poling period are respectively changed to 1.55 and 29.50 μm, wide DFG tuning operations around 3.4 μm are also achieved with the crystal temperature adjusted to adapt the change.

“…Considering the application in remote sensing, pulsed 900 nm lasers will be extremely useful, especially high repetition rate oper ation with a high peak power is in demand for improving the speed and distance in transmission. Usually, the technologies of mode locking or Q switch were used to generate high repetition rate lasers [13][14][15][16]. In the past few years, pulsed quasi three level Nd 3+ doped lasers had been demonstrated by using passively Q switch or acousto-optically (A-O) Q switch.…”

A diode pumped high repetition rate acousto-optically (A-O) Q switched Nd:YVO 4 laser operating at 914 nm was reported in this paper. Employing a compact linear laser cavity, at an operating rep etition rate of 10 kHz, a maximum average output power of 2.2 W 914 nm laser was obtained at an incident pump power of 45.3 W, corresponding to an optical conversion efficiency of 4.9% and a slope efficiency of 8.8%. Minimum pulse width of 24 ns and maximum peak power of 8.0 kW of 914 nm laser was also achieved at an incident pump power of 40.8 W. To the best of our knowledge, this is the highest peak power of 914 nm laser at 10 kHz by far. Moreover, the highest operating repetition rate of pulsed 914 nm can even reach 100 kHz.
