SHIPS TODAY: AeroDIODE offers a wide range of turn-key solutions for the alignment of complex laser systems. These ultra-stable Fabry–Pérot or DFB laser diode sources with PM fiber have an excellent PER (Polarization Extinction Rate). They are either in stock or available in less than 2 weeks lead time. The user can adjust the temperature which adjust the emission wavelength over a wavelength range of up to 10 nm. The key modules for this application are based on laser diodes emitting at 808 nm (for example for petawatt lasers), 1064 nm, 1310 nm or 1550 nm.

CNI offers various laser diode modules with a collimated output beam or with line-shaped output, which are suitable as alignment lasers. Many different colors are available, e.g. red, green and blue.

The fiber-coupled laser diode beam sources of type 51nano-S have reduced power noise (< 0.1% RMS (< 1 MHz)), reduced coherence length (≈ 300 µm) and a low speckle contrast as a result of the internal RF modulation. They are available with wavelengths from 405 nm to 1550 nm.
