atomstack

 If the spare laser on your  Atomstack A5 Pro  is broken, or you're just looking for more power, adding an 8.5W Endurance Laser is a great option. Since the A5 Pro is already set up for PWM control and has a similar laser form factor, the transition is simple. The 8.5W laser is especially suitable for this machine as it is very small and lightweight, allowing for fast acceleration for fast engraving. Since the A5 Pro is built so solidly, you can easily install 10W on it too if you're looking for more power. The steps will be very similar to what is shown here, just the spacing of the mounting holes will be slightly different. To mount the 8.5W laser to an existing Atomstack system, you will need a mount that will accommodate the hole spacing. For height adjustment, we can reuse the existing system as it offers various installation possibilities. All we need is a small adapter that will allow us to use different hole spacings. If your laser is still running, you can easily...

 "Laser" is an acronym, and the five letters of the word come from the initials of the phrase "light amplification by stimulated emission." Electrons in atoms can absorb energy from light or heat only if there are transitions between energy levels that match the energy carried by photons or phonons. For light, this means that any given transition will absorb only one specific wavelength of light. Photons with the correct wavelength can make electrons jump from lower energy levels to higher energy levels. Photons are consumed in the process. When an electron is excited from one state to a higher energy level with an energy difference ΔE, it doesn't stay in that state forever. Eventually, a photon will spontaneously emerge from a vacuum with energy ΔE. Energy is conserved, electrons transition to unoccupied lower energy levels, to different energy levels with different time constants. This process is called "spontaneous emission". Spontaneous emission is...
