Page 17: Laser Head Setup
Chapter 2: Laser System Setup Laser Head Setup The laser head should be mounted on an optical table or equivalent strong flat surface. There are three mounting holes provided to secure the laser. The laser should be installed in a clean environment. In the direction of the laser output beam, a power meter with the power scale up to 30 W should be installed approximately 1.5 feet away from the laser. -
Page 18: Edrive Setup
Chapter 2: Laser System Setup eDrive Setup Input Power Use only power cords suitable for the driver. Use a power source that delivers voltage in the range of 100 VAC (RMS) to 240 VAC (RMS) and 47 Hz to 63 Hz. Power switching is performed automatically (i.e., there are no configuration switches to set for high or low voltage ranging). -
Page 19: Chiller Setup
Chapter 2: Laser System Setup Chiller Setup Ambient Temperature and Relative Humidity The chiller is designed for indoor installation in ambient temperatures between 5 °C and 30 °C (41 °F and 86 °F). Relative humidity should not exceed 80% (non-condensing). Location The chiller should be installed on a strong, level surface and be located as close to possible to the laser. - Page 20 Please follow the proper procedures to clean the chiller before it is connected to the laser head. These procedures are listed on the CD (compact disc) shipped with the unit. They are also available through Northrop Grumman customer service. WARNING.

Page 33: Laser Performance Optimization
For this procedure, a green light should be visible from the laser. In the absence of any visible output, contact Northrop Grumman for assistance. To obtain the best performance, small adjustments may optimize the laser. To optimize the laser, follow these steps: 1. - Page 34 Chapter Three: Laser Optimization and Tuning The coolant flow rate and temperature have a significant impact on the laser performance. Make sure that the flow rate and temperature correlate to the values listed on the ATP test report. Peak up the laser power by tuning the temperature of the TE Controller. Beginning with the TE Temperature from the ATP, adjust the temperature up and down in 0.2°...

Page 36: Check Hold Off
Chapter Three: Laser Optimization and Tuning Perform the same procedure with the vertical adjustments of the HR and HM mount. Periodically check for hold off when making these adjustments (see Check Hold Off section below). If laser power is within +/-5% of nominal (typical power meter accuracy), and it has good beam shape and stability, stop and replace the access screws in the cover. - Page 37 Chapter Three: Laser Optimization and Tuning CAUTION. The output beam of this system is a safety hazard. Avoid viewing the beam directly. Turn On Procedure Switch the chiller to the ON position. Verify correct flow rate and temperature setting to value specified on laser ATP test report data summary. Wait until the chiller has achieved proper temperature, which may take 5 to 10 minutes.
- Page 38 Chapter Three: Laser Optimization and Tuning CAUTION. Never look at the laser beam even it is off because the laser beam will ramp up the power automatically. Shut Down Procedure Press SHUTTER button to stop lasing. Gradually decrease operating current to zero. Press EMISSION on the eDrive to cease diode emission.
