A RF Control System For Frequency Stabilization Of Diode Pumped Nd:YAG-KTP Laser To Doppler-Broadened Absorption Line Center

This thesis describes the system of frequency stabilization of a Nd:YAG-KTP laser to Doppler-Broadened absorption lines of ??The first part buildes up the mathematical model of the frequency stabilization laser; discusses its steady state in detail. The second part describes the design of the RF system to realize frequency stabilization of the laser. It includes three main parts: narrowband match of electro- optical crystal, design of RF drivers and design of detection circuit. Provided the clew of design and realize narrowband matching- of electro-optical crystal in RF band; developed the active phase shifter so that it could be used in RF system and simulated the experiment result by a computer. The last part of the thesis discusses the technology of resisting disturbance used in RE system.
