66 -- SOLID STATE LASER SOL 848000700011BJ DUE 011797 POC BJ Roberts (303) 497-3799 The necessary specifications include: 5 Watts output at 532 nm, in pure TEM00 mode, with M-squared measure of 1.2 or less. It is essential that the basic design of the laser system be such that the output power in single mode regime can be increased in the future as the product line evolves: this means the vendor must have already demonstrated at least 8 Watts output from a laboratory model. Slow frequency variations associated with lab vibrations should be acceptable, but higher frequency perturbations such as would be associated mode-jumping and/or with water-immersion cooling and arc lamp pumping would contaminate our experiment and are unacceptable. Consequently it is necessary that the Nd laser material be pumped by a diode laser source(s), to assure high efficiency and thus avoid the requirement for water-immersion cooling. Intensity variations are also extremely important for our OPO experiment, with rms intensity noise to be below 0.1% rms in a bandwidth from 0.1 Hz to 10 MHz. (If vendor'sbasic laser cannot meet this specification, a user access to the pump diode current shall be provided so that we can ensure the needed intensity stability by our own external servo system. An appropriate port would allow up to 1% diode laser intensity control with 30 MHz control bandwidth and a time delay below 10 nanoseconds.) No RFQ package will be issued. (0361)
