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  OAI收割 Optoelectronic Materials and Devices for Optical Communications, November 7, 2005 - November 10, 2005, Shanghai, China 作者:  Sun Y.;  Wang L.;  Wang L.;  Wang L.;  Liu Y. 收藏  |  浏览/下载：23/0  |  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.
