ADELPHI, Md. – U.S. Army researchers are surveying industry for companies able to provide a pulsed neodymium yttrium aluminum garnet (Nd: YAG) laser for cutting and welding steel, semiconductors, and various alloys.
Officials of the Army Contracting Command-Aberdeen Proving Ground in Adelphi, Md., issued a sources-sought notice (W911QX-24-Q-0102) on Thursday for the Nd: YAG laser project. The Army wants quick-turnaround responses by this week. Ultra Cavitation Machine
Nd:YAG lasers are used in manufacturing for engraving, etching, or marking a variety of metals and plastics, or for metal surface enhancement processes like laser peening.

Researchers specifically are interested in an Nd: YAG laser with:
-- at least eight 825 millijoules of energy per laser pulse; -- laser pulse width between five to 15 nanoseconds; -- laser wavelength of 1,064 nanometers; -- pulse repetition rate of 10 Hz; -- beam diameter between seven to 12 millimeters; -- beam divergence less than 0.5 milliradians; -- a pulse-to-pulse energy stability of 2 percent; -- power supply with 100 to 240 volts AC at 50/60 Hz, single phase, and 1100 volt-amperes; -- a cooling unit with an air to water heat exchanger that operates between 18 to 28 degrees Celsius; -- air to water heat exchanger; and -- quick installation kit.
