These laser diode modules are well-suited for integration by OEMs because they produce high-quality beams at low cost. The modules can be used in medical, industrial, and R&D environments. They offer stabilized optical output power in good quality TEM mode beams that have a M2 quality measurement less than 1.5. (A perfectly Gaussian beam has an M2=1.) The modules incorporate collimating optics within their compact, lightweight anodized aluminum housings. The collimated beams offer a divergence of less than 0.5 mrad; in other words, 10 m from the module, the beam diameter is within 3 x 2 mm. The modules are also focusable.
