[21] Suzanne Jenniches patented laser soldering in 1980. [22] Wavelengths are typically 808 nm through 980 nm. The beam is delivered via an optical ...
Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not necessarily allowing for bullet drop, windage, distance between the direction of the beam and the axis of the barrel, and the target mobility while ...
