The Green DPSS laser is a very complicated photonic/optical device. They make excellent CW transmitters. Power outputs range from 5mw-20W. QRP? Not really. Remember high school physics. E=H/Lambda (wave length. To avoid physics, this equation states that Energy is a function of wavelength. Higher frequencies or wavelength are far more energetic.
A cheap 5mw laser has a range of 5000meters or 7500 feet. A 100mw green laser is visible up to 75 Kilometers (125,000 feet, or 50 miles.) Needless to say this is absolute line of sight.
