A DCM laser dye doped Alq film serves as the active layer. High reflective and low loss electrical contacts are used to form a high quality factor coupled microcavity. Single longitudinal cavity mode is obtained at 618 nm with a threshold current density of 612 mAcm-2 under room temperature continuous wave operation. 2012 SPIE.
	High power VCSEL device with periodic gain active region (EI CONFERENCE) 会议论文 OAI收割 Optoelectronic Materials and Devices II, November 2, 2007 - November 5, 2007, Wuhan, China 作者: Zhang Y.; Liu Y.; Liu Y.; Liu Y.; Qin L. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 High power vertical cavity surface emitting lasers with large aperture have been fabricated through improving passivation lateral oxidation and heat dissipation techniques. Different from conventional three quantum well structure a periodic gain active region with nine quantum wells was incorporated into the VCSEL structure with which high efficiency and high power operation were expected. The nine quantum wells were divided into three groups with each of them located at the antinodes of the cavity to enhance the coupling between the optical field and the gain region. Large aperture and bottom-emitting configuration was used to improve the beam quality and the heat dissipation. A maximum output power of 1.4W was demonstrated at CW operation for a 400m-diameter device. The lasing wavelength shifted to 995.5nm with a FWHM of 2nm at a current of 4.8A due to the internal heating and the absence of active water cooling. A ring-shape farfield pattern was induced by the non-homogeneous lateral current distribution in large diameter device. The light intensity at the center of the ring increased with increasing current. A symmetric round light spot at the center and single transverse mode operation with a divergence angle of 16 were observed with current beyond 4.8A.
	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：21/0 \| 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%.
	The room-temperature lasing of microdisk lasers (EI CONFERENCE) 会议论文 OAI收割 Optoelectronics, Materials, and Devices for Communications, November 12, 2001 - November 15, 2001, Beijing, China 作者: Lin J.; Wang L.; Wang L.; Wang L.; Liu Y. 收藏 \| 浏览/下载：38/0 \| 提交时间：2013/03/25 Multiple quantum wells (MQW) microdisk lasers are fabricated by using the methods of photolithography-etching techniques. By the CCD watching-control and micron-area detecting systems the 5m-diameter microdisk lasers was optically pumped by Ar+ pulse laser at room temperature with the 1:50 pump duty cycle. We obtained the single-mode lasing at 1.543m wavelength with threshold pump power about 200w.
