Direct
light-emitting indium gallium nitride green (InGaN) diode laser
operating in continuous wave output power and efficiency under the new
world record As early as in the global set off a direct indium gallium
nitride light-emitting green (InGaN) diode laser study of fever prior
to Osram Opto Semiconductors researchers have made numerous key
breakthroughs. In the United States at the 2010 San Francisco,
Photonics West (Photonics West 2010) on, Stephan Lutgen a team led by
Dr. the first to demonstrate directly the green light-emitting indium
gallium nitride (InGaN) at 515 nm wavelength of up to 50 mW of
continuous-wave output power The research and development data.
Laboratory Data: Direct indium gallium nitride light-emitting green
(InGaN) laser can emit 50 mW of continuous-wave output power, rewriting
a world record. As a result, OSRAM Opto Semiconductors to erect a
mobile laser projection area of a major new milestone. The optical
power level for the screen, the beam energy of 10-15 lumens of RGB
scanning beam laser projection is necessary. Commercially available
control plane GaN substrates formed by the green laser emission laser
diode as shown. In addition, the presentation of a comprehensive energy
efficiency was 2.7%, indicating Youxiang successfully displays the
direct laser light green indium gallium nitride (InGaN) diode laser a
major step forward. To successfully achieve the true green laser
emission of continuous wave operation, the need to remove several key
barriers. First of all to be done, may be greater than or equal to 515
nm wavelength green emission caused by the required amount of
high-indium light emission active layer (InXGa1-XN quantum potential
well) and a low crystalline quality. Epitaxial growth process of Ga /
In alloy fluctuations and point defects to minimize the achievement of
a higher level of continuous wave output power is very important. OSRAM
Opto Semiconductors, vice president of research and development, Dr.
Volker Haerle, said: "These compact green laser light-emitting diodes
directly will achieve high efficiency and output power, is bound to
change completely the moment the green laser market." |
