In this paper,a LD-end-pumped Nd∶YAG all-solid blue laser(473 nm) is demonstrated using intracavity frequency-doubling with a LBO crystal.

The recording laser shift from red laser to blue laser in next generation optical storage.

In LD pumped intracavity frequencydoubled blue laser,lownoise stable output could be realize by using two identically crossed placed doubler and one Polarized plate which could successively eliminate the coupling between different modes and the scomponents and the pcomponents through the mode competing and the selective loss.

The formation of intermolecular aggregation is the main reason for the phenomena that the photoluminescence (PL) efficiency of trimeric phenylenvinylene (TPV) and its derivatives, which are bright pure blue emitters, is much weaker in solid state than that in dilute solution (over 90%).

In this letter blue TEOLEDs based on the blue emissive material,4,4′-bis(2,2′-diphenylvinyl)-1,1′-biphenyl,are acquired with the choice of a highly transparent cathode together with the utilization of a light outcoupling layer onto the cathode,in which microcavity effects,especially for multiple-beam interference,are restrained by decreasing the reflectivity of the cathode.

Wide-gap materials are widely used in OLEDs, such as short wavelength light-emitting (blue and UV) layers, most hosts for electrophoshporescence, some hosts for electrofluorescence (especially for blue ones), and charged carrier and exciton blocking.
