Spectra-Physics R2-740 Laser Power Supply 90-132V 3A 1PH 47-63Hz Rackmount

Spectra-Physics R2-740 Laser Power Supply 90-132V 3A 1PH 47-63Hz Rackmount

The Spectra-Physics R2-740 is a rackmount laser power supply designed to drive a range of continuous-wave (CW) and pulsed solid-state and diode laser systems. Manufactured in June 1996 by Spectra-Physics Lasers, Inc. of Mountain View, California, it accepts a single-phase AC input of 90–132V at 3.0A / 47–63Hz. The front panel features a green Emission indicator LED, an ENM elapsed-time hour meter, and a J1 Remote D-sub interface connector; a multi-conductor cable is included.

Applications

Spectra-Physics is one of the founding names in commercial laser technology, and the R2-740 power supply is representative of the high-stability, rack-integrated laser drive systems the company produced for research, industrial, and OEM applications through the 1990s. Per its rear-panel labeling, this supply is compatible with CW GaAlAs diode lasers, Q-switched and CW Nd:YAG and Nd:YLF solid-state lasers, and IR and second-harmonic-generation (SHG) systems — covering a broad cross-section of the laser types commonly found in spectroscopy, materials processing, laser pumping, holography, and scientific research labs of that era. The J1 Remote interface connector allows external control or interlock integration, a standard requirement in safety-governed lab and industrial environments. The ENM elapsed-time meter is used to track service intervals and tube or diode life. Units of this type remain sought after by researchers, labs, and laser integrators maintaining or rebuilding legacy Spectra-Physics laser systems.
