Open Beam Butterfly MM

The multi-mode configuration is for customers seeking high laser power vs a single mode operation. While is spatially outputs a line shape, it maintains excellent wavelength stabilty. The laser’s stabilized peak wavelength remains “locked” regardless of case temp. (15 to 45ºC). TE cooling is external, and internal is available upon request. Multi-mode laser diodes come standard with <0.1nm (0.8nm typical) spectral linewidth.
