a laser is just a focused beam of light
Ordinary light is emitted from various sources with different phases and wavelengths, leading to random and constantly changing interference patterns. This lack of a fixed phase relationship between light waves prevents ordinary light from being coherent. Coherent light sources, like lasers, have a single wavelength and phase, allowing for stable interference patterns.
White lasers are different from traditional lasers because they emit light across a broad spectrum of colors, while traditional lasers emit light of a single color. This allows white lasers to be used for a wider range of applications, such as in lighting, displays, and medical imaging, compared to traditional lasers which are typically used for precision cutting, welding, and communication.
A laser produces coherent light that is monochromatic, meaning it emits a single color or wavelength of light. In contrast, ordinary light consists of multiple wavelengths, producing a range of colors. This is why lasers are often used in applications that require precise and specific colors.
Yes, lasers can produce light of different colors depending on the materials used in the laser and its operating conditions. Some lasers emit a single color of light, while others can emit multiple colors simultaneously.
Lasers use coherent light, which means the light waves are all in sync and travel in the same direction. This is what allows lasers to be powerful and focused on a small area.
Lasers have only one colour & are focused on an area while ordinary light is made of the colours you see in a rainbow and fan out.
Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.

No, most lasers emit light at a different frequency than UV.

That would be hard, if not impossible. Lasers work purely by reflection back from an object. Colour information comes from the frequency of light. Your detection equipment would have to simultaneously detect the laser light and the different frequencies of light.
Lasers emit highly concentrated beams of coherent light, typically within a narrow range of wavelengths. This focused light can have various applications in areas such as construction, medicine, communication, and entertainment.
