Tunable coherent emission is generated in a single-pass,cascaded wavelength conversion process from mode-locked laser-pumped monolithic periodically poled lithium niobate(PPLN).Three ranges of wavelength,including visible output from 628 nm to 639 nm,near-infrared output from 797 nm to 816 nm,and ...
Using this method, it has been shown that the characteristics of the laser system at a wavelength of 871 nm are appropriate to control the quantum state of an optical qubit on a quadrupole transition in an ytterbium ion with a n-atural width of 3.1 Hz....

the light wavelength ranges from 250 to 500 nm [Fig. 4(c)]. The gate voltage was set as −1 V, −4 V, −6 V, −8 V and 6 V, respectively. It was found that when a negative gate voltage was applied, a photocurrent peak can be...
The extremely high peak intensity associated with ultrashort pulse width of femtosecond laser allows us to induce nonlinear interaction such as multiphoton absorption and tunneling ionization with materials that are transparent to the laser wavelength. More importantly, focusing the femtosecond laser beam ...
wavelength-dependent focal length, or a different element. Then, once the light illuminating the display is switched between different basic color ranges (e.g., between red, green and blue), the adjustable focal length of this element is adjusted such to compensate a change of the focal ...
Finally, beam imaging and focusing of multi-octave spanning THz pulses are demanding and less-developed than for other wavelength ranges1. Recently, the advance of intense THz sources towards E0.1 GV m À 1 field strength enabled first observations of nonlinear light matter interactions2–6, ...

(excitation: 561 nm, emission: 572–614 nm and 660–728 nm). Two emission channels at different wavelength ranges were used and recombined during post-processing to avoid pixel saturation. DAPI signal was simultaneously acquired (excitation: 405 nm, emission: 416–490 nm). Pixel size was ...
