Lightwave Electronics 126-1064-010 Laser w/ Analog Power Supply
This laser was purchased for a specific project and use a few months and has been sitting on the shelf for years unused. Original purchase price $6,475. We believe the unit to be in working order.

Lightwave Electronics' Series 126 products are single-axial-mode, continuous wave output Nd:YAG laser.
Each laser produces narrow linewidth, frequency stable, single axial mode output. Diode pumping is incorporated for reliability, compactness and efficiency. At the heart of the Series 126 laser is a patented (US patent 4579793) monolithic, traveling-wave ring resonator, referred to as the NPRO (Non-Planar Ring Oscillator). The NPRO ensures stable, single-frequency operation over a wide range of operating conditions. The Series 126 is designed for OEM and individual user applications. It differs slightly from typical lasers in that the laser head can be operated stand-alone or with an optional Lightwave Electronics power supply.
Typically a laser system consists of a head, which contains the optics and optical pump toproduce laser light, and a separate power supply, which provides the drive voltages and other inputs to operate the laser head. However, the Series 126 laser head incorporates many of the electronics, in addition to the resonator, optics and optical pump.
Within the laser head is a hermetically-sealed package (gold box) which contains the solid-state laser diode and NPRO. Other components within the gold box include beam shaping and turning optics and a photodiode used to monitor the laser output from the NPRO.Also within the laser head, but external to the gold box, are electronics which provide the appropriate drivers for the diode current, the diode thermo-electric cooler (TEC), crystal TEC and other controls. As a result, the Series 126 can be driven directly with the proper DC voltage inputs. If the user wishes to use standard wall plug AC voltage, this can be accommodated by using an optional Lightwave Electronics power supply.
Optional Lightwave Electronics Power Supply
As mentioned, the Series 126 can be driven either with DC voltages or with an optional Lightwave power supply. Two different Lightwave Power Supplies are available: the Model 125/126 and the Model A125/126. Both models convert standard wall plug AC voltages (85 to 265 VAC, 50 to 400 Hz) into usable DC voltages for the laser head. The Model 125/126 is microprocessor-based and allows for easy access to, and control of, many laser functions. The Model A125/126 is analogbased, and provides a low cost alternative, while sacrificing some of the convenience of the Model A125/126.
