IR & Blue Dual‑Wavelength Laser Module Kits

1064nm 2W IR + 435nm 20W Blue Laser Module for Multi‑Material Laser Engraving

BU‑LASER presents the IR & Blue Dual‑Wavelength Laser Module Kit, an all‑in‑one hybrid laser solution combining 1064nm 2W infrared (IR) laser module and 435nm 20W high‑power blue laser module, exclusively engineered for multi‑material laser engraving, marking, and precision processing. This dual‑wavelength kit perfectly complements the material‑processing strengths of IR and blue lasers: IR laser excels at permanent metal marking, while blue laser delivers high‑speed non‑metal cutting/engraving. Integrated with unified 24V PWM control, air‑cooled heat dissipation, and industrial‑grade safety protection, it enables one‑machine multi‑material processing, widely used in DIY engraving machines, desktop laser marking equipment, and small industrial processing systems.

Core Dual‑Wavelength Synergy Advantages

1. 1064nm 2W IR Laser Module: Permanent Metal Marking & High‑Contrast Engraving

1064nm infrared wavelength: Optimized for all‑metal surface marking, including stainless steel, aluminum, copper, gold, silver, alloy, and anodized metal. It forms permanent black/white high‑contrast engraving marks through photothermal oxidation, with excellent corrosion resistance and wear resistance, ideal for part coding, logo marking, and serial number engraving.

2W stable CW output: Fine focused beam with ultra‑small spot size ≤0.05mm, supporting ultra‑fine text, QR code, and pattern marking without surface deformation. Built‑in APC constant power control ensures long‑term stable marking quality.

IR laser features low reflection interference and strong anti‑ambient‑light performance, suitable for long‑term industrial batch marking.

2. 435nm 20W Blue Laser Module: High‑Speed Non‑Metal Cutting & Engraving

435nm deep‑blue wavelength: Higher photon energy than standard 450nm blue lasers, with 3–5× higher absorption rate for non‑metals (wood, acrylic, leather, paper, PCB, plastic, rubber). It realizes clean, burr‑free cutting and deep engraving with minimal carbonization or yellowing.

20W high‑power output: Supports one‑pass cutting of 8–12mm acrylic, 6–10mm solid wood, and full‑thickness leather/fabric cutting, greatly improving processing efficiency compared to low‑power blue modules.

3. Unified 24V PWM Control: Seamless Switching & Easy Integration

Both modules adopt 24V DC wide‑voltage input (22–26V) and support standard 0–100% PWM modulation (1–5kHz), with independent power adjustment for IR and blue channels. Users can freely switch single‑wavelength or dual‑wavelength simultaneous operation via CNC control systems.

Fully compatible with mainstream engraving software: LightBurn, GRBL, Mach3, LaserGRBL, directly plug‑and‑play with desktop engraving machine control boards, no additional driver modification required.

Independent safety protection circuits for each module, avoiding mutual interference during simultaneous operation.

4. Air‑Cooled Industrial‑Grade Heat Dissipation: Long‑Time Continuous Operation

Each module is equipped with an independent high‑efficiency air‑cooled system (high‑speed fan + thickened aluminum heat sink), zero‑water‑cooling design, maintenance‑free, zero leakage risk.

Stable continuous operation for 8+ hours at full power, suitable for long‑time batch engraving and marking production. Wide working temperature range of 0°C–50°C, adapting to workshop and indoor working environments.

5. Compact Matching Design: Perfect for Desktop Engraving Equipment

Compact overall size, low power consumption, suitable for small‑volume desktop engraving equipment, DIY laser machines, and portable marking devices.
