ABSTRACT OF THE DISCLOSURE Novel laser resonator cavities and laser wavelength tuning arrange- ments are disclosed. A pair of similar spectral dispersion means achieve in the resonator both a colinear region for rays of different wavelengths and a region in which rays of different warelengths coextend separated and substantially parallel. Amplifying medium in an optical cavity following at least a first dispersion means, preferably in the parallel region of a laser having paired dispersion means, enable amplification at the different wave- lengths while limiting their coupling via the amplifying medium. One or a number of apertures disposed in a dispersed path within a laser cavity are positioned to transmit a selected ray or rays and to block rays of unwanted wavelength whereby laser oscillation wavelength is determined. The above features are variously combined to achieve colinear output beams of various wavelengths and injection-type control of laser oscillation. Variable reflecting optics, e.g., a rotary mirror in a dispersed path, preferably i? the near-parallel region of a laser having paired dispersion means, select different dispersed rays for reflection, enabling, e.g., rapid frequency scanning in a colinear output beam.
