“…As was expected, the minimization of the discharge time notably improved the laser performance. This suggested design for a high power actively QS-FL is a cost-effective technology that can find applications in different fields of science and engineering including laser material ablation [19], laser assisted micro-machining [20], supercontinuum generation [21], LIDAR [22] and bio-medicine [23]. We expect that the ideas presented in this article can also be applied to actively QS lasers that are based on other types of active fibers as well as to solid state and gas lasers.…”

Abstract-We report the results of an experimental study aimed at improving the performance of actively Q-switched fiber lasers. Unlike generic design schemes employing photonic crystal fibers, large modal diameter fibers or double-clad fibers, we demonstrate a high-power, actively Q-switched laser based on standard communication erbium doped fibers with peak irradiance beyond the state-of-the-art at 3.1 GW/cm 2 . The laser had 2.2 kW peak power, 15 ns pulse duration, 36.8 μJ pulse energy. We have also investigated the dynamics of pulse generation and have successfully suppressed pulse instabilities caused by backscattered laser emission reaching the pump laser diodes.

“…Furthermore, most literature concerns SC generation in all kinds of special fibers which are mentioned in the above paragraph, less attention has been paid to SC generation in the mid-IR range with use of the cheap and widely commercially available telecommunication MMF pumped by ≥ 2000 nm nanosecond pulse solid laser. Previously, standard SMF or MMF was used to generate mid-IR SC laser pumped by ~1550 nm pulse fiber laser or amplifier [16,17]. In this year, we reported a SC generation in standard SMF pumped by 2054 nm pulse laser, and the obtained maximal power was 0.53 W at 7 kHz [18].…”

Up to ~520 µJ broadband mid-infrared (IR) supercontinuum (SC) generation in telecommunication multimode fiber (MMF) directly pumped by a 2.054 μm nanosecond Q-switched Tm,Ho:YVO4 laser is demonstrated. An average output power of 3.64 W is obtained in the band of ~1900 to ~2600 nm, and the corresponding optic-to-optic conversion efficiency is 67% by considering the coupling efficiency. The spectrum has extremely high flatness with negligible intensity variation (<2%) in the wavelength interval of ~2070 to ~2475 nm. The SC long-wavelength edge is limited by the silicon glass material loss, and by optimizing the MMF length, the SC spectrum could extend out to ∼2.6 µm. The output SC pulse shapes are measured at different output powers, and no splits are found. The SC laser beam is nearly diffraction limited with an M 2 =1.15 in 2.1 μm measured by the traveling knife-edge method, and the laser beam spot is monitored by an infrared vidicon camera.

The mid-IR supercontinuum (SC) light source is in demand for many chemical, biological, medical, and astronomical applications. It is of great significance to develop a mid-IR SC light source whose spectrum is wide and flat.We obtained ultra-broadband mid-IR SC by using a piece of fluoride glass through filamentation. Though the SC generation by filamentation needs a powerful laser chain to be the pump source, it has some advantages in comparison with that based on fiber. First, the optical path length in the glass can be very short due to the adopted high pump power. The negative influence of accumulated loss can be reduced greatly, so the transparent range of glass is much larger than fiber. Secondly, it is convenient in light-coupling, and the coupling efficiency can be high. In comparison with it, the coupling of the small core (usually the core is small to ensure a high nonlinearity) mid-IR glass fiber is troublesome. Thirdly, the glass piece is cost-effective, and can be fabricated easily.We obtained a SC spectrum covering 0.2-8.0 μm by using a 32mm-thick fluoride glass sample. The 3 dB bandwidth covers 1.15-4.76 μm. The 20 dB bandwidth spans from 0.39 to 7.4 μm. The glass thickness, optical path, and pump conditions are optimized to enable the SC to be as wide as possible. This work shows that the SC generation through filamentation in bulk glass can be an effective way to obtain an ultra-broadband mid-IR light source, which will find various applications in mid-IR regions.
