The NIST ytterbium-doped fiber laser used can provide up to 530 watts of laser output at a wavelength of 1.07 microns. At full power, they were able to deliver as much as 3.5 uN (0.35 mg) of force to the mirror. The experiments showed the expected linear relation between measured force and laser output.
It's just the way coffee is. Coffee is acidic. That's what probably upsets your stomach, especially if you're not eating or drinking other fluids throughout the day. People say that using coffee grounds are excellent for growing plants. BUT, they are only good for growing plants that are acidic soil loving plants.
No, coffee doesn't stunt your growth. But coffee does contain caffeine, which stimulates the central nervous system. For most people, a cup or two of coffee a day doesn't do any harm.

That's because high doses of caffeine can cause anxiety and dizziness, and may interfere with normal sleep.
