Spectra-Physics 117A laser power supply

Product Description

Spectra-Physics 117A Laser Power Supply (For Ion Lasers)

This is a Spectra-Physics 117A, a high-voltage, high-current power supply designed to drive argon or krypton ion lasers from the Spectra-Physics 160/170 series or similar. A critical component in vintage scientific, medical, and entertainment laser systems, this supply converts AC line voltage to the precise DC and RF power needed to excite the laser plasma tube. Sold AS IS for parts, repair, or restoration of legacy Spectra-Physics laser systems.

Key Features (Typical of 117A Series):

• Input: 208–240V AC, single or three-phase, 50/60 Hz

• Output: High-voltage DC (kV range) and RF excitation for plasma ignition and sustainment

• Control: Analog control boards with current regulation, interlock safety, and remote interface

• Cooling: Likely includes internal fans and heat sinks; may require external cooling

• Connections: High-voltage cables, interlocks, and remote control connectors

• Compatibility: Designed for Spectra-Physics 161, 162, 165, 171, 177 and similar ion lasers

Potential Uses:

• Vintage Laser Restoration: Donor supply for restoring a Spectra-Physics ion laser to working condition.

• Component Salvage: High-quality transformers, high-voltage capacitors, RF transistors, heat sinks, and control PCBs.

• High-Power Electrical Projects: Source of robust industrial power components (for experts only).

• Educational/Display: For teaching laser electronics, museum display, or as a prop.

Important Notes:

• Extreme Danger: This unit contains lethal high voltages and large stored energy. Do not power on without proper training and safety gear.

• System Dependency: Requires a compatible Spectra-Physics laser head and interlock system to function as intended.

• Technical Expertise Required: Suitable only for experienced laser technicians, high-voltage engineers, or skilled electronics salvagers.
