| 1 | Petawatt class lasers worldwide显示文摘The use of ultra-high intensity laser beams to achieve extreme material states in the laboratory has become almost routine with the development of the petawatt laser. Petawatt class lasers have been constructed for specific research activities,including particle acceleration, inertial confinement fusion and radiation therapy, and for secondary source generation(x-rays, electrons, protons, neutrons and ions). They are also now routinely coupled, and synchronized, to other large scale facilities including megajoule scale lasers, ion and electron accelerators, x-ray sources and z-pinches. The authors of this paper have tried to compile a comprehensive overview of the current status of petawatt class lasers worldwide.The definition of ‘petawatt class' in this context is a laser that delivers >200 TW. | Colin Danson David Hillier Nicholas Hopps David Neely | 2015 | High Power Laser Science and Engineering2015，3，1： | 16 |

| 3 | A Linearly-Polarized Rubidium Vapor Laser Pumped by a Tunable Laser Diode Array with an External Cavity of a Temperature-Controlled Volume Bragg Grating显示文摘A diode pumped alkali vapor laser has advantages in high quantum efficiency,excellent beam quality,and low thermal effect.We obtain a laser diode array(LDA)with linewidth of 0.20 nm and an external cavity of volume Bragg grating(VBG).Its central wavelength can be tuned from 779.30 nm to 780.10 nm by changing the VBG's temperature.Pumped by this LDA,a 2.1 W rubidium vapor laser is achieved with optical efficiency of 10.5%and slope efficiency of 22.7%. | 李志永 谭荣清 徐程 李琳 赵志龙 | 2013 | Chinese Physics Letters2013，30，3： | 1 |
| 4 | High duty cycle,highly efficient fiber coupled 940-nm pump module for high-energy solid-state lasers显示文摘Tailored diode laser single emitters with long(6 mm) resonators and wide(1.2 mm) emission apertures that operate with940 nm emission wavelength were assembled in novel edge-cooled vertically stacked arrays, and used to construct a compact and highly efficient fiber coupled pump source for Yb:YAG pulsed high-energy class solid-state lasers. The novel configuration is shown to allow repetition rates of 200 Hz at 1 ms pulse duration, at an output power of 130 W per single emitter. The emission of two stacked arrays was then optically combined to realize pump modules that deliver6 kW peak power(pulse energy 6 J) from a 1.9 mm core diameter fiber, with wall plug efficiency of 50%. This represents a significant improvement in terms of duty cycle and electro-optical efficiency over conventional sources. The pump module has been successfully tested at the Max Born Institute, Berlin during trials for pumping of disk lasers. | Ren Platz Bernd Eppich Juliane Rieprich Wolfgang Pittroff Gtz Erbert Paul Crump | 2016 | High Power Laser Science and Engineering2016，4，1： | 1 |
| 5 | EXPERIMENTAL RESULTS ON A GaAlAs LASER DIODE OPTICALLY PUMPED CESIUM BEAM显示文摘Almost all the atoms in the hyperfine sublevel F=4,m_(F)=0('clock level')of cesium ground state have been pumped out by using a laser diode tuned on the Cs-D2 line;and 15.2%population difference(|δoo|)which is more than two times better than what the traditional magnetical selecting state method could provide is found.This experimental result can be applied into building an optically pumped Cs beam frequency standard and better performance will be expected. | WU Xin-xin YAO Shu-tong SHANG Song-quan XUE Jian-wei XIE Lin-zhen | 1985 | Chinese Physics Letters1985，2，1： | 1 |
| 6 | Laser diode stacks:pulsed light power for nuclear fusion显示文摘Laser drivers are an enabling factor to inertial confinement fusion, because laser diodes must be used instead of flash lamps. We discuss the limitations of laser diode arrays and show what steps the industry is taking. The pump power requirements of large-scale projects such as LIFE or Hi PER are within reach of semiconductor laser diode assemblies.Pulsed light output powers per laser bars have been around 300 W per bar, as in the Jenoptik 940 nm bars previously used for pumping the Yb:YAG slabs in the Di POLE project. By redesigning the semiconductor laser structures 500 W per bar is now commercially available for 808, 880 and 940 nm pump wavelengths. The construction of one inertial fusion power plant will require an amount of semiconductor laser chips in excess of the current annual production by two orders of magnitude. This adds to the engineering task of improving the device characteristics a challenge to production capacity.While the industry benefits from the recent boost in solid-state lighting that acts as a technology driver, cooperation between manufacturers will be imperative, and to this end we propose standardization efforts. | Martin Wlz Agnieszka Pietrzak Alex Kindsvater Jens Meusel Klaus Stolberg Ralf Hlsewede Jrgen Sebastian Valentin Loyo-Maldonado | 2016 | High Power Laser Science and Engineering2016，4，2： | 1 |
| 7 | Overview of ytterbium based transparent ceramics for diode pumped high energy solid-state lasers显示文摘Development of high energy laser sources with nanosecond pulses at several hertz values for repetition rate has been very attractive in recent years due to their great potential for practical applications. With the recent advancement in fabricating large size laser quality transparent ceramics, diode pumped solid-state laser generating pulse energy of 100 J at 10 Hz has been recently realized at HiLASE center using Yb:YAG ceramic with Cr:YAG cladding. This review discusses Yb based high energy lasers, specific laser geometries for efficient thermal management and the role of transparent ceramics in such diode pumped high-energy-class solid-state lasers around the world. | Samuel Paul David Venkatesan Jambunathan Antonio Lucianetti Tomas Mocek | 2018 | High Power Laser Science and Engineering2018，6，4： | 0 |
