Is it Possible to Change Light Color with Material?”

In summary, there are wavelength shifting plastics and diode-pumped solid state lasers that can change the color of light, but they can only make it redder, not bluer. The use of a passive material for this purpose would be highly advantageous in the medical and industrial laser industry.

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
 

FAQ: Is it Possible to Change Light Color with Material?”

Can light color really be changed with materials?

Yes, it is possible to change light color with materials. This process is known as color filtering or color manipulation. It involves using materials that can selectively absorb or reflect certain wavelengths of light, resulting in a change in the perceived color of the light.

How does color filtering work?

Color filtering works by using materials called pigments or dyes that have specific molecular structures. These structures determine which wavelengths of light are absorbed and which are reflected. The absorbed wavelengths are then subtracted from the original white light, resulting in a change in color.

Is it possible to change light color without using materials?

Yes, it is possible to change light color without using materials. This can be achieved through the use of colored lights or gels, which are specifically designed to emit or filter certain wavelengths of light. However, this method is not as precise as color filtering with materials.

What types of materials can be used for color filtering?

There are various types of materials that can be used for color filtering, including pigments, dyes, filters, and crystals. The specific material used will depend on the desired color change and the application. For example, pigments and dyes are commonly used in art and fashion, while filters and crystals are used in scientific and technological applications.

Is it possible to change light color in real-time?

Yes, it is possible to change light color in real-time using materials. This is achieved through the use of electrochromic materials, which can change color when an electric current is applied. These materials are commonly used in devices such as smart windows and electronic displays.
