Study of Two-Photon Absorption and Amplification Processes in Gases.

Abstract

This report summarizes our theoretical and experimental findings. It is divided into 8 sections. Section 1 contains a general description of the problem and a summary of the main results. Section 2 contains the theory of two-photon amplification. Section 3 details the requirements for the selection of an appropriate active medium. Section 4 describes the pumping requirements and the handling and preparation of the vapor cell. Section 5 contains a description of the curve of growth method which has been used in the work to measure the density of Calcium vapor. Section 6 describes the details of operation of the pump dye laser and of the second harmonic generation. Section 7 contains a description of the construction and operation of the infrared dye laser. Section 8 contains a description and technical details of the timing circuitry used to fire the pump and probe lasers in a preassigned temporal sequence. (Author)
