Q-SWITCHED HIGH POWER SINGLE FREQUENCY 2 MICRON FIBER LASER ACCURATE MEASUREMENT OF ATMOSPHERIC PARAMETERS…

Public award description

Q-SWITCHED HIGH POWER SINGLE FREQUENCY 2 MICRON FIBER LASER ACCURATE MEASUREMENT OF ATMOSPHERIC PARAMETERS WITH HIGH RESOLUTION NEEDS ADVANCED LASERS. IN THIS SBIR PROGRAM WE PROPOSE TO DEVELOP INNOVATIVE Q-SWITCHED HIGH POWER 2-MICRON FIBER LASER WITH PULSE ENERGY GREATER THAN 10MJ, REPETITION RATE OF 10HZ TO 1KHZ, AND PULSE DURATION OF 200NS USING INNOVATIVE HIGHLY EFFICIENT TM-DOPED GLASS FIBER. THIS NEW FIBER LASER WILL BE AN ALL-FIBER LASER SYSTEM CONSISTING OF ACTIVELY Q-SWITCHED FIBER LASER AND FIBER AMPLIFIERS. THIS PROPOSED ALL-FIBER LASER SYSTEM IS COMPACT, HIGHLY EFFICIENT, ROBUST AND HIGHLY RELIABLE, WHICH IS ESPECIALLY SUITED FOR NASA'S APPLICATION WHERE OPERATING ENVIRONMENT IS ALWAYS EXTREMELY ROUGH. IN PHASE I WE WILL DESIGN AND FABRICATE TM-DOPED GLASSES, DESIGN AND FABRICATE SINGLE MODE AND DOUBLE CLADDING SINGLE MODE TM-DOPED FIBERS, AND DEMONSTRATE Q-SWITCHED SINGLE FREQUENCY 2-MICRON FIBER LASER AND AMPLIFIERS.
