1. A laser comprising:

  • a gain section;

    a wavelength filter;

    a first reflector; and

    a second reflector to form a laser cavity with the first reflector, the laser cavity to include the gain section and the wavelength filter;

    wherein the wavelength filter is temperature stabilized within a predetermined temperature range and the remaining portions of the laser cavity are not temperature stabilized, and wherein the wavelength filter, when at the predetermined temperature range, comprises a plurality of adjacent longitudinal modes such that cavity round-trip modal gain values associated with each of the adjacent longitudinal modes comprise similar values differing by a predetermined delta.
