Abstract
A diode laser utilizing a grazing incidence grating in combination with collimating and refocusing devices and a mirror having a plurality of spaced reflective areas which are effective to return different wavelengths to the grating and thence to the laser to sustain oscillation at the reflected frequencies with tuning of the frequencies accomplished by translation of the mirror to position the reflective areas to change the reflected wavelengths.
