Abstract
A diagnostic unit is used to align and focus individual laser sources in a spectral beam combining (SBC) laser. The diagnostic unit modifies a Shack-Hartmann wavefront sensor to dedicate one or more microlenses to a particular wavelength of the SBC laser using wavelength-specific filters in combination with corresponding microlenses. The diagnostic unit allows all of the laser sources to be evaluated at the same time because each wavelength has a dedicated portion of the sensor, typically a charge-coupled display. When an individual beam is centered in its dedicated portion of the sensor and has an acceptable spot size or intensity, the source for that particular beam is correctly aligned and focused. Off-center or incorrect spot-sized beams indicate incorrect alignment and focus for the laser source for that wavelength. When correctly calibrated, the sensor output can also be used to measure and correct power output levels of the individual laser sources.
