Abstract

An instrument is described for the coaxial alignment of two laser beams, one of which is a continuous wave helium–neon laser, the other one a pulsed neodynium glass laser. The helium–neon laser beam is aligned such that it propagates in the axis of the pulsed laser beam and thus permits observation of changes before, during, and after the occurrence of the pulsed laser event. Although the design emphasized the 1.35-μ sidebands of the neodymium laser, most tests were conducted at 1.06 μ where neodymium in glass ordinarily operates. A residual nonlinearly polarized component of the pulsed laser light caused considerable disturbance in the detection circuit and prevented low level detection of perturbation effects.
