21. The company said it also asked the FDA for clearance to market the EpiTouch Ruby laser for hair removal. 22. Ruby laser pistol constructed by Stanford Univ . physics professor in 1964 to demonstrate the laser to his classes.23. These ruby lasers generate deep red light pulses of a millisecond pulse length and a wavelength of about 694.3 nm. 24. Ruby lasers are still used for a few applications, but they are not common because of their low power efficiencies.25. Ruby lasers produce pulses of coherent visible light at a wavelength of 694.3 nm, which is a deep red color.26. I believe they were originally created for ruby lasers . talk ) 18 : 03, 16 July 2011 ( UTC) 27. The first Raman laser, realized in 1962, used nitrobenzene as the gain medium, which was intra-cavity-pumped inside a Q-switching ruby laser . 28. Dermatologists and plastic surgeons are using ruby lasers that break up pigmented skin or dye to eliminate birthmarks, freckles and tattoos. 29. Specifically, I want one of the easiest cuts, a hemisphere shape, made out of the rod taken from a ruby laser . 30. For example, the first operating laser, a ruby laser , was optically pumped; the helium neon laser is pumped by gas discharge.
