O’FALLON, Mo., March 25, 2013 — Laser distributor RPMC Lasers Inc. has released Areté Associates’ Airtrac, an ultracompact diode-pumped solid-state laser.

The air-cooled laser provides 50 mJ of pulse energy at 1064 nm, with pulse widths of 6-ns full width half maximum and repetition rate capability up to 30 Hz. Despite its size (6.5 cu in/0.43 lb), it features a resonator design that promotes a highly uniform beam. The laser was built on a fundamentally athermal gain module.

The Airtrac design is scalable, allowing for higher pulse energies and the addition of nonlinear optics to reach eye-safe wavelengths. Both the 532-nm and optical parametric oscillator crystals will be internal to the laser and available in the standard packaging.

The device has performed over a temperature range of −40 to 60 °C and is specified to operate at up to 70 °C. Typical applications include laser designation, lidar, LIBS (laser-induced breakdown spectroscopy), ranging and medical.

full width half maximum
Full width half maximum (FWHM) is a measure of the extent of a function. Given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value. The term duration is preferred over width when the independent variable is time. Commonly applied to the duration of pulse waveforms, the spectral extent of emission or absorption lines, and the angular or spatial extent of radiation patterns.
An acronym of light detection and ranging, describing systems that use a light beam in place of conventional microwave beams for atmospheric monitoring, tracking and detection functions. Ladar, an acronym of laser detection and ranging, uses laser light for detection of speed, altitude, direction and range; it is often called laser radar.
