Northrop Grumman Corporation (NYSE:NOC) has received a contract from the U.S. Navy for the continued production of the AN/AES-1Airborne Laser Mine Detection System (ALMDS). The contract includes the production of five ALMDS pod subsystems, support equipment, spares, and technical support.
The ALMDS is mounted on an MH-60S helicopter. Flying over sea lanes, it finds and geolocates mine-like objects with its pulsed laser light and streak tube receivers by imaging, in 3-D, day or night, the near-surface of the ocean.
Cutting Edge Optronics (CEO Laser) recently manufactured the largest, commercially available, diode pumped Nd:YLF laser amplifier in the world. This PowerPULSE series laser amplifier pumps a one inch Nd:YLF laser rod with more than 150 QCW laser diode bars, and produces more than 5 Joules of gain switched energy and over 6 Joules of stored energy.
Northrop Grumman Cutting Edge Optronics (NG-CEO) recently hosted a Science, Technology, Engineering and Math (STEM) student open house for 21 middle and high school students. The students participated in a day full of fun activities, facility tours and lectures. The students played games that taught them some basics of laser alignment and mechanical tube bending. The facility tour also included a demonstration of laser engraving. The students had the opportunity to observe the laser engraving process, and each was given a personalized flash drive with their name inscribed. Continue reading →
Laser drive electronics are a very important consideration when designing any DPSS laser system. Controlling multiple laser system functions and managing the operational and safety interlocks are critical requirements.
Cutting Edge Optronics (CEO) recently manufactured one of the largest commercially available diode pumped laser amplifiers in the world. The laser amplifier pumps a one inch diameter Nd:YAG laser rod with more than 400 QCW laser diode bars, and produces more than 9 Joules of gain-switched energy and over 7.5 Joules of stored energy. This is one example of several large laser amplifiers CEO has manufactured over the past 12 months. In order to keep up with the record demand level for laser amplifiers, CEO has doubled its manufacturing capability in 2014.

Dr. Jun Kojima of the Ohio Aerospace Institute with Dr. David Fischer and Dr. Quang-Viet Nguyen of the NASA Glenn Research Center recently tested a new architecture for SRS laser spectroscopy to realize time-resolved combustion diagnostics. Continue reading →
Ti:Sapphire lasers have become prominent in the field of ultrafast lasers and oscillators due to their broad emission bandwidth and the ability to minimize opto-thermal effects over a wide range of operating parameters. This article examines the construction of a high-power Ti:Sapphire laser from the ground up. Mode-locked lasers are discussed, as are single-pass, multi-pass, and regenerative amplifiers. The use of pulse pickers to help generate higher pulse energies is also discussed.
In order to build high-average-power Ti:Sapphire lasers, high-quality high-average-power green pump lasers are required as pumps for the final amplification stage. This article examines the main requirements on the pump lasers, and also discusses the relative merits of Nd:YAG and Nd:YLF systems.
