Two Bragg gratings (FBGl and FBG2) were employed as the cavity mirrors. The Average output power  single pulse energy and pulse width of the fiber laser at different pumping powers and different repetition rates was studied. The output spectrum of the fiber laser is 0.5 nm. At maximum launched pump power of 558mW  pulse energy of about 50J and duration of 140ns was obtained at the repetition of 2 kHz.   High-power InGaAs VCSEL's single devices and 2-D arrays (EI CONFERENCE) 会议论文 Optoelectronic Materials and Devices for Optical Communications, November 7, 2005 - November 10, 2005, Shanghai, China Li T.; Ning Y.; Sun Y.; Qin L.; Yan C.; Liu Y.; Wang L. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 We report on bottom-emitting vertical-cavity surface-emitting lasers (VCSEL's) and laser arrays providing high output powers in the 980-nm wavelength regime. Single devices with active diameters of 500 m show high output powers of 1.95 W at room temperature. Its threshold current is 510 mA  and the maximum spatially averaged optical power density is 0.93 kW/cm2. A 16 elements array with 200m aperture size (250m center spacing) of individual elements shows a CW output power of 1.21 W at room temperature  resulting in a average optical power density of 1KW/cm2. The threshold current of the array is 1.32A and the lasing peak wavelength is 981.9 nm. The distinction of emission spectrums between the single device and the array is discussed.   Color video display technique based on diode-pumped solid state lasers (EI CONFERENCE) 会议论文 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China Zhang Y.; Liu W.-Q.; Kang Y.-S.; Zhang J.-Y.; Liu H.; Wei Z.-L. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 This paper will introduce the principle and techniques to realize laser color video display. The characteristics of techniques and bottleneck of restricting the development are analyzed. A novel technical approach to eliminating the laser interference  improving the uniformity of optical field  transforming the chromaticity and extending the virtual color is proposed. The principle device of laser display system has been produced on the basis of the blue  green and red diode-pumped solid state lasers. The wavelengths of the blue  green and red are respectively 473nm  532nm and 671 nm. The output powers of the lasers are 1.3W  0.32W and 3.5W respectively.
