E-MAIL: Maria L. Westman, Maria.L.Westman.1@gsfc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFQ FOR ND-YAG Pulsed Laser. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to clarify specifications. The 532nm pulse width is required to be less than 10 nsec. The energy wavelengths should be delivered from a single aperture. The repetition rate will be externally triggered. The applications are related to the GLAS instrument, which operates at 40 Hz. Environmentally the system should operate at temperatures from -10 to 40 C. The lasers will operate in the laboratory and occasionally on a small aircraft. Data on previous use of the lasers in flight or high vibration environments will help in the evaluation of the proposals. The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on 07/14/98.
