Frequently Asked Questions
Q: What power supply does the 520nm green laser PWM module require?
A: This laser module requires a stable 12V / 5A AC power supply to operate correctly. Using an undersized or unstable power supply may result in reduced performance or damage to the module.
Q: Can the 520nm laser module be focused to a tighter beam?
A: No — this module features a fixed, non-focusable beam. The beam is expanded to approximately 30mm (3cm) in diameter at the exit via an integrated beam expander. The design is optimized for wide-area visibility and ground marker use rather than pinpoint focusing.
Q: How does PWM/TTL modulation work with this laser module?
A: The module supports PWM (Pulse Width Modulation) and TTL modulation via a 0–5V signal input at frequencies below 18KHz. This allows you to adjust the laser's output power dynamically using a compatible controller, microcontroller, or signal generator.
Q: Is this laser module safe for outdoor bird deterrent use?
A: This module is suitable for outdoor bird deterrent applications and can effectively deter birds within approximately 100 meters under direct sunlight. Always follow local regulations regarding laser use outdoors and ensure the beam path is clear of people and animals at all times.
