The technique of SFG is also being used in the development of compact blue CW light sources based on near-infrared diode lasers. Resonantly enhanced SFG of several mW of blue light near 460nm by mixing a single-mode diode laser with a diode-pumped 1064-nm Nd:YAG laser was demonstrated by...
a The graph shows the frequency of HPV genotypes found by LA as single (pink bars) or multiple infections (blue bars). b The graph shows the percentages of single (pink bars) or multiple infections (blue bars) calculated for each individual HPV genotype, considering the number of samples ...
We discuss the implications of an experiment in which the frequencies of two laser beams are compared for different intensities in order to search for a dependence of the frequency of light on its intensity. Since no such dependence was found it is possible to place bounds on a description of...

Blue or violet light can also be generated by frequency doubling (external to the laser resonator or intracavity) the output of lasers emitting around 800–1000 nm. Most frequently used are neodymium-doped lasers, e.g. Nd:YAG emitting at 946 nm (for 473 nm), Nd:YVO4 at 914 nm (for 45...

In the temporal domain, their waveforms had the same periodic structure (blue dots, Fig. 2A, bottom panels) but different fine structures in each period. If the neural response is a simple tracking of F0 contour, then similar responses would be expected for these F0 modulated stimuli. However...
