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.   LD-Pumped all-solid-stated green laser with high polarization rate and high conversion efficiency (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices for Optical Communications, November 7, 2005 - November 10, 2005, Shanghai, China Hao E.-J.; Tan H.-M.; Yan C.-L.; Qian L.-S. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 A high-power-output and high polarization rate Nd:YVO4/ KTP green laser has been presented. By analyzing the factors which affect the conversion efficiency and polarization rate  we used a short folded-cavity resonator  the maximum output power of 320 mW is obtained at 532 nm with the LD pumping power of 1 W  the optical-to-optical conversion efficiency is 32% and the polarization rate is 550:1.   Color video display technique based on diode-pumped solid state lasers (EI CONFERENCE) 会议论文  OAI收割 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Liu H.;  Wei Z.-L.;  Liu H.;  Liu H.;  Kang Y.-S. 收藏  |  浏览/下载：22/0  |  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.
