The team noticed that when the pump laser reached a certain power, the intensity of the light emitted by the sample increased sharply.
3 Diode laser delivery via the transscleral route is inefficient, with only 35% of laser energy reaching its intended target.
The laser power reaching the sample surface was 20 mW, and the typical acquisition time was 60 s.
An interesting feature was the larger backwall photoconductivity (with the laser beam reaching the film from the substrate side), when compared to photoconductivity in the normal, frontwall illumination.
When too many Au nanoparticles gather on the top of SiO2 nanorods, they would form larger particles and prevent the incident laser from reaching the Au nanoparticles adhering on the side of the nanorods.
We verified that 50 mW laser power reaching the specimen plane and focused on the growth cone did not affect its motion for at least 1 h.
Even for the portion of the laser light reaching the sample, the light does not scatter directly upward but rather will scatter off of the opaque walls of the plate, limiting the amount of light that reaches the detector.
The tibiae of eight OVX mice were treated for 5 days each week for 2 weeks by LLLT (660 nm, 3 J) using a minimally invasive laser needle system (MILNS) which is designed to minimize loss of laser energy before reaching bone (LASER group).
Because laser ablation is induced when the laser fluence reaches 1012 1014 W/m2, which is less than that for laser-induced breakdown (1015 W/m2), laser ablation can generate a lower sound pressure, and the sound source has a hemispherical radiation pattern on the surface where laser ablation is generated.
Peyghambarian says there are no physical showstoppers preventing his photorefractive polymers and lasers from reaching that goal, although he says that doing so will require the use of faster pulse lasers, among other things.
