520nm 1W Green Dot Laser Module TTL PWM – Bird Deterrent
520nm 1W Green Dot Laser Module with TTL/PWM Control
The Elubor 520nm Green Dot Laser Module is a compact, high-performance 1W (500mW) green laser designed for a wide range of professional applications — from stage lighting and engraving machines to bird deterrent systems for airports, orchards, farmland, warehouses, and power grid installations. Operating at a precise 520nm wavelength, this laser delivers a vivid, focused green beam with adjustable focus and power control via PWM/TTL signals.
Made in Mainland China.
Key Features
- 520nm Wavelength: Produces a brilliant, highly visible green dot beam ideal for professional and industrial applications.
- 1W / 500mW Output Power: Powerful beam suitable for engraving dark cardboard, stage effects, and outdoor bird deterrent use.
- Adjustable Focus: Fine-tune the beam spot to suit your specific application needs.
- Burst Flash Mode: Toggle between continuous emission and adjustable-frequency flashing mode using the onboard knob. Note: Flash mode adjusts frequency only — not laser power.
- PWM/TTL Power Control: Precisely adjust output power using a 0–5V PWM signal (frequency <18kHz). Must be set to constant light mode to use PWM power adjustment.
- 12V DC Operation: Operates at 12V nominal voltage via AC power source. Includes a DC head and adapter for direct 110–240V socket use.
- Engraving Machine Compatible: Comes with a 3-PIN to 4-PIN cable and a 3-PIN cable for engraving machine motherboard connection. Please confirm motherboard compatibility before purchase.
- Mini Form Factor: Compact, self-contained design for easy integration into existing setups.
Bird Deterrent Application
Green lasers in the 520–532nm wavelength range are uniquely effective as bird deterrents. Birds are highly sensitive to green light, and when the laser beam scans nearby, it triggers a natural visual response, causing birds to perceive a moving threat and flee the area. This makes the module an excellent tool for:
- Airport runway and tarmac bird management
- Orchard and farmland protection
- Warehouse and storage facility bird control
- Power grid and infrastructure protection
- Evening and night-time deterrent operations
The laser can also be adapted for use as a highway fatigue-warning light or mounted on vehicles as a visual alert signal.

⚠️ Important Safety Notices
- Eye Hazard: This laser module emits a powerful beam. Never direct the beam at eyes or allow eye contact — doing so may cause permanent vision damage. Always follow proper laser safety protocols.
- Keep Away from Children: This is not a toy. Keep out of reach of children at all times.
- Fire Hazard: Do not use near flammable materials or in environments containing combustible gases.
- Engraving Limitations: This module can only engrave dark cardboard. It cannot engrave or cut metal, transparent materials, white surfaces, or reflective plastics.
- Do Not Disassemble: Opening the module may cause irreparable damage and voids any warranty.

Frequently Asked Questions
Q: What is the difference between burst flash mode and continuous mode on this green laser module?
A: In burst flash mode, the laser alternates between on and off states at an adjustable frequency set by the onboard knob — however, only the frequency is adjustable in this mode, not the laser output power. In continuous mode, the laser emits a steady, uninterrupted beam, and power can be controlled externally via a PWM/TTL signal (0–5V, <18kHz). You must switch to continuous mode before using PWM power adjustment.
Q: Can this 520nm green laser module be used with any engraving machine?
A: This module includes a 3-PIN to 4-PIN cable and a 3-PIN cable for engraving machine integration. However, compatibility depends on your engraving machine's motherboard connector type. Please verify your machine's specifications before purchasing. If needed, the cable configuration can be changed. The module can also be powered directly from a 110–240V wall socket using the included DC head and adapter.
Q: How effective is this green laser as a bird deterrent?
A: Birds are particularly sensitive to green light in the 520–532nm wavelength range. When the laser beam scans across an area, birds perceive it as a moving visual threat and naturally flee. This module is well-suited for evening and nighttime deterrent use in open environments such as airports, orchards, farmland, warehouses, and power grid areas. Results may vary based on bird species, environment, and usage conditions.
Q: Does this laser module require any external power supply?
A: Yes. The module operates at 12V DC and requires an external power source. It does not include batteries. For direct wall outlet use, a DC head and 110–240V adapter are available. For engraving machine use, the included cables connect to the machine's power and control board.
