The Newport 5501 High Power Laser Diode Driver is a current-control module engineered for stable, precise operation of high-power laser diodes in demanding applications. It delivers output current up to 100 A at 14 V compliance, with integrated protection architecture designed to prevent overcurrent damage and extend diode longevity.
– Technical Specifications
• Output Current: up to 100 A
• Compliance Voltage: 14 V
• Power Supply: +15 Vdc and −15 Vdc (for indicator illumination and circuit operation)
• Form Factor: Module
– Key Features
The 5501 incorporates multiple protection layers critical for high-power laser diode reliability:
• Adjustable current limits
• Redundant hardware current limits
• Slow start circuitry
• Output shorting relays
• Transient protection
These safeguards mitigate overcurrent events and transient conditions that would otherwise degrade or destroy sensitive laser diodes. The adjustable architecture allows tuning to specific diode requirements while hardware redundancy provides fail-safe operation.
– Typical Applications
The 5501 is suited for systems requiring high current delivery to laser diodes with precision control and fault protection. Industries leveraging such drivers include industrial laser manufacturing, medical laser systems, and laboratory research environments where diode stability and protection are non-negotiable.
– Compatibility & Integration
Designed for integration into laser systems requiring precise current control, the 5501 accepts high-power laser diodes as the primary load. The module operates as a standalone unit within larger system architectures.
Safety and Operational Requirements: Proper ventilation must be maintained around cooling apertures. Power cords and signal cables should be routed to prevent mechanical damage. Do not operate equipment showing signs of shipping or impact damage—contact technical support for assessment before powering the unit. Service and adjustments require qualified technician involvement.
