This report describes the ultrashort pulse laser system, USP-II, installed in the research laboratory and which is comprised of components manufactured by both Spectra-Physics and Coherent Laser Group. This laser system uses state of the art laser technology to provide very high energy single pulses in the visible and near IR spectra for pulsewidths near 100 femtoseconds This report describes in detail the turn-on and operating procedures so that the system operator can bring it up to specificationc and fine-tune the subsystems to give optimum pulsewidth and energy pulse outputs. The basic system has been configured to operate on a single 4 by 12 ft optical bench with some diagnostic instruments permanently mounted to the table. The major subsystems which comprise the USP-II are described briefly as to their operating characteristics and how the output characteristics of each unit affects the output of the following unit. This report is not designed to replace the operating procedures of each subsystem but rather to describe how the complete system works in unison. Each subsystem is described ir the same order as required to turn on the system and reach specified outputs. The theory of operation is incorporated into this turn-On procedure along with optimizing procedures. If any subsystem output does not meet its specifications, the operator is referred to the manufacturers operating and maintenance procedures for that particular laser. Correct output signals for each laser are described and optimizing procedures for obtaining these optimum levels are also described. This report should be adequate for the daily operation of the system if no problems occur within any subsystem.
