chrisbaird said:Higher frequency beams carry more energy (E = hf). In order of lowest frequency to highest, and therefore least destructive to most, we have: radio waves, terahertz, infrared, visible light, ultraviolet, x-rays, gamma rays. That is why x-rays can give you cancer but infrared does not. In free space, wavelength and frequency are trivially related, f = c/lambda, so that higher frequencies are always shorter wavelengths. You only need to talk about one and other is understood.
That being said, the ability of a laser to damage an object depends on many things: the intensity of the laser beam, the spot size to which the beam is focused, and the way in which the specific material responds to the beam (which is frequency dependent).
thalion777 said:that doesn't seem possible considering that frequency and wavelength are totally different.
I am not sure about your plans. I have seen some HS textbooks and they typically do not discuss design of laser systems. So, assuming you are looking at some advanced concepts, you should have in your possession a college textbook just to get a peek at what lies ahead. And to see if you are able to deal with the math. And please do online research.also, would a high school physics textbook work?
i am not even in chemistry as i am a sophomore in high school. i am trying to get ahead in science as i have a knack and an interest in physics and inventing and have always been at the head of my class
A high power laser is a device that produces a powerful and concentrated beam of light through the process of stimulated emission. This means that the laser beam is created by stimulating atoms to release photons of light in a controlled and coherent manner. High power lasers are used in a variety of applications, such as cutting and welding, medical procedures, and scientific research.
The power of a laser is typically measured in watts (W), which represents the amount of energy that the laser emits per unit of time. For high power lasers, the power can range from a few watts to several thousand watts. The power of a laser can also be measured in terms of intensity, which is the concentration of power over a given area.
High power lasers can affect the nature of light waves in several ways. First, they can increase the intensity and coherence of the light, meaning that the waves are more concentrated and aligned. Second, they can change the properties of the light waves, such as their polarization or wavelength. Third, high power lasers can even create new types of light waves, such as terahertz waves, which have important applications in science and technology.
The frequency and wavelength of light are closely related to the power of a laser. The frequency of light is a measure of how many waves pass a given point in a second, while the wavelength is the distance between two consecutive wave peaks. In general, high power lasers have shorter wavelengths and higher frequencies, which means that the light waves are more energetic and can carry more information.
High power lasers are an essential tool in scientific research, as they allow scientists to study and manipulate light at extremely high levels of intensity and precision. They are used in fields such as optics, materials science, chemistry, and physics to understand the fundamental nature of light and its interactions with matter. High power lasers are also used in cutting-edge technologies, such as particle accelerators and fusion reactors, to push the boundaries of scientific discovery.
