| Introduction to Diode Laser Assemblies | Diode Laser Assemblies are readily available at wavelengths varying from 408 nm to 1.6 µm and above, and at output power ranging from a few milliwatts to several watts. Because of their small size and exceptional efficiency, diode lasers have replaced the HeNe laser in many OEM applications, particularly in those where beam quality and wavelength stability, and unit-to-unit repeatability are not critical. Melles Griot does not manufacture laser diodes! It does manufacture diode laser assemblies that include beam-conditioning optics, automatic power control (APC), temperature control, environmentally sound packaging, and any other features required to meet your exact design goals. | Cool Tips |
| Introduction to Helium Cadmium Lasers | The helium cadmium (HeCd) laser is a member of the same laser family as the HeNe, and is the only relatively economical, continuous-wave (cw) source of violet (442-nm) and ultraviolet (325-nm) output. Because of its excellent match to photo polymer and film sensitivity wavelength ranges and its good beam quality, it is used extensively for three-dimensional stereolithography applications, as well as for creating embossed holograms | Cool Tips |
| Introduction to Helium Neon Lasers | The helium neon laser was the first laser to be used in volume applications. Currently, there are millions of HeNe lasers in the field, and only the semiconductor diode laser is produced in greater volume. The key to the HeNe's success has been its low cost, small size, long operating life (as much as 50,000 operating hours), and unsurpassed beam quality. HeNe lasers produce milliwatts of output power and are available in a variety of wavelengths ranging from 543 nm (green) to 1.523 μm (infrared). The most common wavelength is the familiar 633 nm (red). These lasers are small, convection cooled, and can be operated from ordinary household power or even from batteries. | Cool Tips |
| Introduction to Solid-State Lasers | Diode-pumped solid-state (DPSS) microchip lasers are an exciting new tool for OEM applications that combines the beam quality of a gas laser and the small size and efficiency of a diode laser with single-line output in the blue (473 and 488 nm), green (532 nm), or yellow (561 nm). | Cool Tips |
