Blue-light generating femtosecond wavelength-tunable non-collinear optical parametric amplifierThe present invention discloses a means of the generation of tunable femtosecond pulses from 380 nm to 465 nm near the degenerate point of a 405-nm pumped type-I BBO non-collinearly phase-matched optical ...
Absolute spectral irradiance values for daylight and the different light sources were weighted by wavelength to estimate the associated biological effects corresponding to IPD, PPD, and oxidative stress. For calculations of the biological effective irradiance of different light sources with respect to PPD...
Therefore, it was hypothesized that direct stimulation of the blind-spot with short-wavelength light would induce a retrograde effect on retinal ganglion cells, measurable by PERG, and that their interaction with bipolar cells in the IPL could be evaluated through the b-wave of full-field ERG (...
Irradiation was done by a LED based system (# LZ1-00UA05 BIN U8; LedEngin, San Francisco, CA, USA) constructed in our lab which radiates blue light of wavelength 405 nm. The LEDs were arranged in a 2 × 3 grid pattern. All the irradiation and EF stimulation steps were carried out ...
The need for thin foil welding is increasing significantly, particularly in the electronic industries. The technologies that are currently available limit the joining processes in terms of materials and their geometries. In this paper, a series of trials
Wavelength of Blue Light Visible light is a form of energy and part of the electromagnetic spectrum. Radio waves, microwaves, X-rays, and other kinds of light are also part of the electromagnetic spectrum, but visible light is the only part of it human eyes can see. ...
doping and downsizing effects11,12. Fortunately, the color conversion could be adopted to avoid these weaknesses by applying blue chips to photo-excite the narrow-bandgap emitters, such as phosphor, II–VI quantum dots, or perovskites, for efficient long-wavelength (>550 nm) emissions13,14. ...
By varying the amount of indium, the band gap and emission wavelength are also tunable. In theory, the accessible wavelength range for InxGa1 − xN alloys spans from 365 nm (GaN) to 1771 nm (InN), providing coverage of the entire visible spectrum. However, beyond ∼480 nm the ...
