Abstract: A system may include a first light source configured to generate a first beam of light at a first wavelength; a second light source configured to generate a second beam of light at a second wavelength; a third light source configured to generate a third beam of light at a third wavelength; and a fourth light source configured to generate a fourth beam of light at a fourth wavelength. The system may also include a thin-film filter, a first polarization beam splitter (PBS), a wave plate and a second PBS. The thin-film filter, the first PBS, the wave plate, and the second PBS may be configured to combine the first beam, the second beam, the third beam and the fourth beam into a combined beam of light.
