CEO regularly makes presentations on its latest technical developments at conferences and tradeshows around the world. Here are a selection of technical papers that describe some of our research and development activities.
| Technical Note #19 - Expected Lifetime of RBA and RBAT Laser Gain Modules | |
 |
Accelerated life test data is presented and analyzed in order to predict the expected lifetime of RBA and RBAT laser gain modules under typical operating conditions. Based on these results, estimated lifetimes of 30,000 - 120,000 hours are predicted. Additional information concerning the impact on lifetime from operating at derated current is also presented ...READ MORE |
| Technical Note #18 - Laser Pulse Train Amplification with PowerPULSE™ Modules | |
 |
Northrop Grumman Cutting Edge Optronics (NGCEO) has developed a line of laser amplifiers specifically for high-energy, quasi-CW operation. The PowerPULSE™ laser amplifiers can operate at high pump powers for pumping times on the order of milliseconds. This allows high amplification factors over longer times at lower thermal loads ...READ MORE |
| Technical Note #17 - kW-Class, Wavelength Stabilized Laser Diode Arrays | |
 |
Northrop Grumman Cutting Edge Optronics has developed a process for building high-power laser diode arrays with narrow emission spectra by adding Volume Bragg Gratings during the packaging process. These arrays emit with a spectral width of approximately 0.5nm (FWHM), and are available with output powers ranging from tens of watts to several kilowatts...READ MORE |
| Technical Note #16 - QCW Diode Array Reliability at 8xx nm | |
 |
Northrop Grumman Cutting Edge Optronics has recently developed high-power laser diode arrays specifically for long-life operation in quasi-CW applications. These arrays feature a new epitaxial wafer design that utilizes a large optical cavity and are packaged using AuSn solder and CTE-matched heat sinks. Reliable operating points are identified for various applications including range finding (product lifetimes less than 1 billion shots) and industrial machining (product lifetimes greater than 20 billion shots) ...READ MORE |
| Technical Note #15 - High Density Laser Diode Arrays | |
 |
Northrop Grumman Cutting Edge Optronics has developed a new 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. The HDS laser package enables power densities of approximately 25 kW/cm2...READ MORE |
| Technical Note #14 - PowerPULSE Gain Modules | |
 |
Northrop Grumman Cutting Edge Optronics has developed a family of Quasi-CW pumped gain modules with output energies is excess of 4 Joules and small signal gains of over 600. The PowerPULSE™ gain modules can be configured with rod sizes from 2mm to 10mm and diode bar counts of 3 to 300. Quasi-CW pumped module lifetimes exceeding 10,000 hours and 20 billion shots are available...READ MORE |
| Technical Note #13 - Reliability of High Power QCW Arrays | |
 |
Northrop Grumman Cutting Edge Optronics has developed a family of arrays for high-power QCW operation. These arrays are built using CTE-matched heat sinks and hard solder in order to maximize the reliability of the devices. The life tests demonstrate the high level of reliability of these arrays in a number of operating regimes. A MTTF of 19.8 billion shots is predicted...READ MORE |
