Schawlow

In the end, I decided to remain at Stanford, accepting a promotion to full professor in 1975, and I continued to work close to Art Schawlow for another 11 years before returning to my native Germany in 1986.

I had first met Art Schawlow, co-inventor of the laser, at a summer school at Carberry Tower in Scotland in 1969, and I was immediately captivated by his warmth, his keen mind, and his contagious sense of humor.

Discussing possible ways to increase the interaction time of hydrogen atoms with a laser beam, Art Schawlow and I came up with the idea of laser cooling of atomic gases in early 1974.

When I arrived at Stanford, I told Art Schawlow about the interesting experiments at Bell Laboratories, and I proposed that I would like to try and make a nitrogen laser pumped dye laser so highly monochromatic that it could be used for Doppler-free saturation spectroscopy of gaseous absorption lines.

Our early work with hydrogen was prominently cited when Art Schawlow received the Nobel Prize for laser spectroscopy in 1981.

Finally, because Bell Labs was very big on solid state physics in those days, Schawlow suggested using solid state materials for the lasing medium.

Laser cooling of neutral atoms was proposed in 1975 by T.W. Hänsch and A.L. Schawlow.

Charles Townes and Arthur Schawlow developed the LASER light amplification by stimulated emission of radiation in order to utilize the possibility of cohering light into a narrow beam.
