trini said:actually i was thinking more along the lines of a suspended dot as it were (in midair) that would be the same colour as the lasers being used. perhaps more specifically, if a tried to make a standing wave out of red light using laser pulses, would it appear as though i had a 'string' of stationary red pulses in midair?
sophiecentaur said:If you could find the right nonlinear medium, it could be possible to 'generate' light (em with a visible frequency) by beating two high intensity em waves of a higher frequency than that of light (ultraviolet) and forming an intermodulation produce with a frequency equal to the difference between the two input frequencies. The visible light would only be produced in the region where the beams overlap.
cjameshuff said:A rather different mechanism, but I recall reading some time ago about a 3D display using two-photon fluorescence in a special glass that glowed in visible light when illuminated by near-infrared lasers of two specific wavelengths, but was transparent to each alone (at least, at the intensities used). Ah, here:

Intersecting laser pulses refer to the phenomenon where two or more laser beams cross paths and interact with each other. This can result in various effects, such as interference patterns, energy transfer, or even the creation of new wavelengths.
Intersecting laser pulses are used in a variety of scientific applications, including spectroscopy, microscopy, and particle acceleration. By controlling the timing, intensity, and direction of intersecting laser pulses, researchers can manipulate and study the properties of matter on a very small scale.
Intersecting laser pulses are typically created using high-powered lasers and sophisticated optics. The timing and direction of the pulses can be controlled using mirrors, lenses, and other optical components. The intensity and wavelength of the pulses can be adjusted using various techniques, such as amplification or frequency conversion.
Intersecting laser pulses can be extremely powerful and can cause damage to human eyes and skin. Therefore, it is important for researchers to follow strict safety protocols, such as wearing protective eyewear and operating the lasers in a controlled environment. Additionally, care must be taken to prevent accidental exposure to bystanders or other sensitive equipment.
Over the years, there have been numerous advancements in intersecting laser pulse technology, such as the development of ultrafast lasers, which can produce pulses in the femtosecond (10^-15 seconds) range. This has opened up new possibilities for studying and manipulating matter at the atomic and molecular level. Additionally, the use of adaptive optics and computer algorithms has improved the precision and control of intersecting laser pulses.
