The 0.3 nm Problem: How Heat Shifts a Laser’s Wavelength
A laser diode’s wavelength isn’t fixed. As it heats up, the semiconductor’s bandgap shrinks and its cavity shifts, pushing emission toward the red, sometimes in sudden mode hops. Learn why it happens, why drive current matters too, and how TECs and smart design keep optical performance stable.

Beyond Wavelength + Power: How to Specify an OEM Laser
Wavelength and optical power are only the starting point when specifying an OEM laser. Beam size, divergence, working distance, modulation, packaging, thermal conditions, electrical interfaces, and production requirements can all determine whether a laser will actually work inside the final system.
