A folded waveguide gain media, RF-driven, CO2 laser can produce stable CW, mode-locked, and Q-switched waveforms for laser radar applications. This type of laser, designated the Multiple-Folded Laser (MFL), has its folded, mm bore waveguide cut into a flat, ceramic tile. A 1-meter folded gain length MFL has a 4.5 kg mass, a 2-liter volume and produces 22 W CW optical output power. A 3-meter MFL produces 90 W CW and 40 W mode-locked CW average power. The current 3-meter MFL has a 4.5 kg mass and a 6-liter volume. MFL technology is evolving to higher power in lighter mass and a 6-liter volume. MFL technology is evolving to higher power in lighter, smaller packages. The Phase I SBIR demonstrated that a pair of 3-meter MFLs can operate in a Master Oscillator Power Amplifier (MOPA) configuration and poduce pulsed waveforms with amplified, average, optical output power of 100W. The proposed Phase II SBIR provides plans to design, fabricate, test and characterize a compact, monolithic MOPA MFL that locates a 6-meter MO and 6-meter PA stage very close together in a single, 0.03 m3, sealed gas container < 0.03 m3 to produce over 400 W CW optical output power and 30,000 W peak power at variable PRFs up to a few kHz. Fourteen government and four commercial candidate applications of the monolithic MOPA MFL are identified for LADAR and LIDAR sensing of hard and gaseous targets
