In continuous mode, the laser emits a steady, uninterrupted beam, and power can be controlled externally via a PWM\/TTL signal (0–5V, \u0026lt;18kHz). You must switch to continuous mode before using PWM power adjustment.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this 520nm green laser module be used with any engraving machine?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How effective is this green laser as a bird deterrent?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this laser module require any external power supply?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between burst flash mode and continuous mode on this green laser module?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.
