Lasing action in electrically pumped organic laser device is demonstrated. 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.

With the advantages of small volume
light weight
high efficiency and long lifespan
diode laser has been widely applied to industrial processing. Presently
for laser used as processing light source needs to amount to dozens of KW per cm2 of power density
how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing
808nm laser array composed of 20 bars eventually achieves the 1001.5w power output
coupling efficiency at 90%
11mm2 of light spot through experiments
which enables diode laser to be directly applied to cladding
welding and so on. 2012 IEEE.

Lithium fluoride (LiF) crystal is a very promising candidate as nanometer resolution EUV and soft X-ray detector. Compared with other EUV and soft X-ray detectors
charge coupled device and photographic films
LiF crystal has high resolution
large field of view and wide dynamic range. In this paper
using LiF crystal as EUV detector and a Schwarzschild objective (SO) working at 13.5nm as projection optics
mesh images with 4.2 m
1.2 m and 800 nm line width and pinhole patterns with 1.5m diameter are acquired in projection imaging mode and direct writing mode
respectively. Fluorescence intensity profiles of images show that the resolution of mesh image is 900 nm
and the one of pinhole image is 800 nm. In the experiments
a spherical condense mirror based on normal incidence type is used to eliminate the damage and contamination on the masks (mesh and pinhole) caused by the laser plasma
and the energy density is not decreased compared with that the masks are close to the plasma. The development of the SO
the alignment of the objective and the imaging experiments are also reported. 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
