Melles Griot manufactures a wide variety of laser types with output ranging from the ultraviolet to the near infrared. We offer three basic types of lasers: gas lasers (helium neon, helium cadmium, and ion lasers), diode-pumped solid-state (DPSS) lasers, and semiconductor diode laser assemblies.
-
Helium neon (HeNe) lasers are available with output in the red, green, orange, yellow, and infrared spectral regions. They are low in cost and have unsurpassed beam quality, but have relatively low output power (up to 30 mW).
-
Helium cadmium (HeCd) lasers operate in the deep blue (violet) or
ultraviolet spectral region.
-
Air-cooled ion lasers produce output at a wide variety of wavelengths throughout the visible spectral region. They are available in single-line (wavelength), multiline, and line-tunable configurations. Multiline output power is as high as 400 mW.
-
DPSS lasers combine the low power consumption of the HeNe with the high output power of an ion laser. These lasers are available with output in the blue green, and yellow spectral region with output power as high as 3 W.
-
Semiconductor diode laser assemblies are used extensively in OEM applications. They operate in the violet (deep blue), red and near-infrared spectral regions with output power up to 50 mW. They are quite small, use very little power, and have very long operating lives. In general, external beam conditioning is required for optimum beam quality.
In addition to lasers, Melles Griot offers a variety of instrumentation to measure critical beam characteristics such as power, mode, beam shape, and beam quality (M2).
