Single-Mode Lasers have a higher beam quality than multimode lasers. Typically, a laser with an M2 value less than 1.3 is regarded as ‘single-mode.’
The spatial mode structure of a diode laser is determined by the ridge width of the waveguide, similarly as the core of a fiber-optic cable. For single-mode laser diodes, the ridge width is determined by the wavelength of the laser but is typically between 3 to 10 microns wide. Such a narrow waveguide allows for single transverse electric (TE) and transverse magnetic (TM) modes to be supported resulting in a perfect TEM00 beam profile. The limited volume associated with having such a narrow active area results in far less power generation and much larger power densities at the facet, but it also results in a much lower capacitance allowing for quicker switching, therefore, making single-mode laser diodes far superior for high-speed applications. Single-mode laser diodes are available in both free space and fiber coupled packaging configurations.
