Webb1 okt. 2024 · In 1958, Townes and his brother-in-law, A. L. Schawlow, published a paper titled, “Infrared and Optical Masers” that detailed how masers could work in optical realms. The optical maser, called a laser, was granted a U.S. patent number 2,929,922. Webb9 juni 2004 · Recent interest in the application of infrared and optical masers (lasers) for range measurement, surveillance, welding, and drilling has focused attention on the problem of obtaining high peak‐power pulses of short duration and fast risetime from these quantum devices. Kerr cells, Pockel cells, rotating disks, and mirrors have been used …

WebbLaser frequency fluctuations can be characterized either comprehensively by the frequency noise spectrum or in a simple but incomplete manner by the laser linewidth. A formal relation exists to calculate the linewidth from the frequency noise spectrum, but it is laborious to apply in practice. We recently proposed a much simpler geometrical …
