60mW 940nm VCSEL SMD Diode

60mW 940nm VCSEL SMD Diode Laser

Advantages:

Wavelength stability: The lasing wavelength in 60mW 940nm VCSEL SMD Diode is very stable, since it is fixed by the short (1~1.5- wavelength thick) Fabry-Perot cavity. Contrary to edge-emitters, VCSELs can only operate in a single longitudinal mode. 

Wavelength uniformity & spectral width: Growth technology has improved such that 60mW 940nm VCSEL SMD Diode are produced with less then a 2nm standard deviation for the cavity wavelength. This allows for the fabrication of VCSEL arrays with little wavelength variation between the elements of the array (<1nm full-width halfmaximum spectral width). By contrast, edge-emitter bar-stacks suffer from significant wavelength variations from bar to bar since there is no intrinsic mechanism to stabilize the wavelength, resulting in a wide spectral width (3~5nm FWHM).
