	Q-switched Er/Yb co-doped cladding pumped fiber laser (EI CONFERENCE) 会议论文 OAI收割 Passive Components and Fiber-based Devices IV, November 2, 2007 - November 5, 2007, Wuhan, China 作者: Liu Y.; Liu Y.; Liu Y.; Wang J. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 A compact all fiber Q-switched fiber laser based on an Er/Yb co-doped fiber (EYDF) is demonstrated. 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 energy long duration frequency-doubled Nd:YAG laser and application to veins occlusion (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: Li D.; Guo J.; Guo J.; Tang Y.; Zhang L. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 Laser treatment represents an attractive option to other methods of vessel diseases especially varicose veins. A long pulse (30-50ms) 532nm laser (Fig.1) is used in our experiments with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood. Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5J-energy pulse allows us to finely occlude rabbit or dog's vein vessels up to 2 mm in diameter when irradiating them off external skin (Fig.2). Blood vessels are occluded at once and later biopsy specimens show the immediate and long-term lasting occlusion effect. While irradiating vessels directly (Fig.3) the vessels are usually irradiated to perforate detailed causes are still under investigation. Animal experiments show long pulse green laser therapy is a safe and effective solution to the vein's occlusion which promises such laser with high energy of each pulse and 30-50 ms duration is an ideal candidate for vessel diseases treatment.
