	All fiber ytterbium-doped fiber grating laser (EI CONFERENCE) 会议论文 OAI收割 High-Power Lasers and Applications III, November 8, 2004 - November 11, 2004, Beijing, China 作者: Zhang L.; Wang L.; Wang L.; Wang L.; Ning Y.-Q. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 Based on requirement of all fiber structure all fiber Yb-doped fiber grating laser uses double cladding fiber with Yb-doped as gain medium uses fiber grating as resonance cavity and employs semiconductor laser as pumping source to realize the lasing based on the reverse of Yb ion. We use Bragg fiber grating as the resonance cavity of fiber laser and 970nm LD as pumping source pump the Yb-doped double cladding fiber with circular inner-cladding. We realized 7.5 W single-mode laser output central wavelength of 1080nm FWHM of 0.11 nm under the pump power of 11.8W. Maxim conversion efficiency is 63.5 % and slope efficiency of 46.4%.
	Research on LD-Pumped dual wavelength Nd:YAG Laser with high beam quality for machining (EI CONFERENCE) 会议论文 OAI收割 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者: Zhang G.; Zhang G.; Zhang G.; Zhang J.; Zhang J. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 Considering laser medium thermal lens effect and thermal focal length changes with pumping power conventionally lasers are designed to operate in the middle of thermal stable zones where the fundamental mode size is insensitive to thermal perturbation while this method seems impossible when large fundamental mode size is required. Through self-select mode cavity lasers are designed to work at the border of stable zone instead where large fundamental mode size in gain media can be reached. With increase of pumping power and self-aperture mode-selective effect mode size would grow up automatically to a certain value suitable for monomode resonance. With double 180 W pump modules acoustic Q-switch and LBO external frequency-doubled over 28 W which M2 equals 4.5 quasi-CW output green laser and 52W 1.064 um IR output is obtained simultaneity. With the insertion or not of the harmonic separator by footswitch high beam quality green IR and green IR lasers are obtained conveniently.
