Sirah Lasertechnik is a privately owned German manufacturer of scientific laser systems, founded in 1998. Based in Grevenbroich, the company develops, engineers, and manufactures tunable lasers for research and scientific applications, with a product range spanning continuous-wave and pulsed systems. Its offerings include single-mode CW ring lasers using dye or titanium-sapphire designs, as well as high-energy and high-repetition-rate pulsed lasers.

Systems are available for applications requiring broad wavelength coverage, narrow linewidths, high pulse energy, or high average power. Sirah also supplies frequency-conversion units for UV/VIS and IR/MIR wavelength generation, along with laser dyes, dye circulators, and related accessories. Its pulsed laser systems are used in atomic and molecular spectroscopy, among other applications.

The company provides product information, downloads, contact and support services, and access to worldwide distributors. Sirah Polska, a related private company established in 2006, manufactures mechanical components from materials including aluminum, stainless steel, brass, and plastic, and produces many of the mechanical parts used by Sirah Lasertechnik
