FURTHER INFORMATION
1 1064 nm only
2 Nominal factory configuration. For OEM applications energies can be optimized to favor a specific wavelength, which in some cases can double the specified energy. Energy output @ 5Hz.
3 Beam widths are measured at the output window of the laser. Beam widths are measured using the second moment energy distribution.
4 Beam divergence is full angle. Beam divergence is determined by measuring the widths of the transformed beam by an aberration-free focusing element, one focal length away from the rear principle plane of the element.
5 RMS stability is defined as: (standard deviation)/(mean). RMS Stability is measured using the full laser beam for 1000 shots after a 100 shot turn-on at 5Hz operation.
6 Energy Variance is defined as: (max-min)/(max+min). Energy Stability is measured using 98% of the pulses of the full laser beam for any 100 shot interval, after the initial 100 shot stabilization from turn-on, up to 1000 shots of 5Hz operation.
7 Pulsewidth is measured at 5Hz PRF. The energy shall be within ± 10% of the specified energy when pulse width is measured. Pulsewidth is calculated from the full-width half-maximum (FWHM) of the waveform.
8 Pointing stability is measured on the 1064 nm laser output. It is measured as theangular shift between the centroid of the beam for the 1st pulse and the centroid of the beam exhibiting the strongest angular shift within the first 1000 consecutive shots at 5Hz operation. Measurement is far field, measured with an aberration-free focusing element, one focal length away from the rear principle plane of the element.
