BLUEDIODE LASERS The recent achievement of compact blue-emitting gallium nitride semiconduc- tor lasers is likely to have far-reaching technological and commercial effects. The lasers’ short wavelengths— around 400 nm, half that of gallium arsenide-based lasers—permit higher spa- tial resolution in applica- tions such as optical storage
The blue LD-based UWOC system enables 11.6-Gbps 16-QAM OFDM transmission over 3.4 m with an average SNR of 15.4 dB and a BER of 3.2 × 10 −3. The penalty for expanding the underwater distance to 6.8 m is a decrease in the data rate to 8.8 Gbps, with corresponding SNR of 15.2 dB and BER of 3.8 × 10 −3.
Shuji Nakamura' development of a blue semiconductor laser on the basis of GaN opens the way for a host of new applications of semiconductor lasers. The wavelengths can be tuned by controlling the composition. For the first time it is possible to produce lasers with various wavelengths, ranging from red through yellow and green to blue, in one substrate material. This fact, together with their ...
Here, Dr. Nakamura discusses the physical concept and basic manufacturing technology of these new blue light-emitting and laser diodes. he shows how this represents a new era in commercial applications for semiconductors, including displays, road and railway signalling, lighting, scanners, optical data storage, and much more.

High power blue laser diodes provide void-free, spatter-free welds on copper, non-ferrous metals, and dissimilar metals. In addition to blue diode lasers, diode-pumped solid-state (DPSS) lasers are also available offering extremely long coherence lengths for applications such as Interferometry, Holography, and LIBS. DPSS lasers can produce blue ...
The blue laser is a device that emits a light beam in the wavelength range between 400 nm and 500 nm. The light beam produced is temporally coherent and can be well-collimated, which allows it to have numerous applications in industry and science. Characteristics of different blue lasers are predominantly determined by different gain media and ...

By pre-leveling the sidelobe filtered OFDM subcarriers, the P.C.-lens collimated 120-mW BLD beam enlarges the 16-QAM OFDM transmission capacity up to 18 Gbps even with a little degra- dation of 0.4 Gbps during 16-m free-space transmission, which is much higher than the capacity of 13.6 Gbps provided by the 80-mW BLD/Obj.-lens/p-i-nPD set.
