SUMMARY

It is not currently possible to create a material that changes the color of light from a longer wavelength to a shorter wavelength, such as from 650 nm (red) to 420 nm (blue). Existing wavelength-shifting plastics can only reduce the energy of light, making it redder, but not bluer. The discussion references diode-pumped solid-state lasers (DPSS), which generate 808 nm and emit 532 nm (green), highlighting the limitations of current materials in achieving the desired effect. Such advancements in passive materials would have significant applications in the medical and industrial laser fields.

PREREQUISITES
  • Understanding of light wavelengths and their properties
  • Familiarity with laser technology, specifically diode-pumped solid-state lasers (DPSS)
  • Knowledge of wavelength-shifting materials and their limitations
  • Basic principles of optics and photonics
NEXT STEPS
  • Research the properties of wavelength-shifting plastics and their applications
  • Explore advancements in laser technology, focusing on diode-pumped solid-state lasers (DPSS)
  • Investigate potential materials for passive wavelength conversion
  • Study the principles of photonic crystals and their impact on light manipulation
USEFUL FOR

Physicists, optical engineers, materials scientists, and professionals in the medical and industrial laser sectors seeking to understand the limitations and possibilities of light manipulation technologies.

Hello , I'm new in here.

I'm not physicist , but I wonder if it is possible to have such material , that changes the color of the light. For example we take a piece of glass , we shoot it with a LASER beam of light with 650 nm wave length ( redish ) and the beam , escaping the glass would be for example 420 nm .

Is there such material like this glass ? Or something similar ?

There are wavelength shifting plastics. Note that these only can reduce the energy of the light - make it redder, never bluer.
 
You might review the principle of a diode-pumped solid state laser (dpss). Using a crystal these generate 808 nm and emit 532 nm (green). Not what you're looking for but I suspect as close as you will get.

In the medical/industrial laser field, such a passive material as you are describing would be hugely beneficial
