A laser (100) produces light having multiple wavelengths. The laser (100) comprises a gain medium (110) disposed within the laser resonator cavity (160), a dispersion element (120) coupled to the gain medium (110) and within the laser resonance cavity (160), and a wavelength-selective element (130) coupled to the dispersion element (120) and defining an end of the resonance cavity (160). The wavelength-selective element (130) has non-abutting reflective segments (131). At least one of the multiple wavelengths corresponds to a position of at least one segment from the non-abutting reflective segments (131).
