STEM Student Open House

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.

Record Demand for CEO Laser Amplifiers

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.

Ti:Sapphire Laser Overview

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.

Pump Lasers for Ultrafast Amplifiers

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. In order to build high-average-power Ti:sapphire lasers, high-quality high-average-power green pump lasers are required.

Cutting Edge Optronics (CEO) offers the Patara-HP family of Q-switched green lasers, which are ideally suited as pump sources for pulsed Ti:sapphire amplifiers. The performance of the Patara-HP pump lasers is examined in this work, particularly the 100W and 200W average power systems. An analysis of pulse energies at varying repetition rates, beam quality and stability, pulse-to-pulse stability, long-term power stability and beam pointing stability is presented. A discussion of laser system reliability is also included.

HDS laser diode packaging increases power density by 2.5X

Northrop Grumman Cutting Edge Optronics has developed a laser diode array package with  minimal bar-to-bar spacing. These High Density Stack (HDS) packages allow for a power density increase on the order of ~ 2.5x when compared to industry-standard arrays.

This work contains an overview of the manufacturing process, as well as representative data for 5-, 10-, and 20-bar arrays. Near-field and power vs. current data is presented in each case. Power densities approaching 15 kW/cm² are presented. In addition, power and wavelength are presented as a function of pulse width in order to determine the acceptable operational parameters for this type of array. In the low repetition rate Nd:YAG pumping regime, all devices are shown to operate with relatively low junction temperatures.

A discussion of future work is also presented, with a focus on extending the HDS architecture to reliable operation at 300W per bar. This will enable power densities of approximately 25 kW/cm².
