Laser Diode 905nm 25W (EMC)

Product Overview

Leirte PLD905‑75W‑P is a high‑power cost‑optimized plastic‑molded Pulsed Laser Diode (PLD) with triple stacked epitaxial emitters, aimed at long‑coverage Time‑of‑Flight distance‑sensing systems.

For OEM developers pursuing longer detection range but still needing to control component cost for mass production, this 905nm infrared pulsed laser diode provides stable 75W application‑grade peak power within economical non‑hermetic through‑hole plastic packaging. Both gold‑plated and silver lead‑frame versions are offered to match varied product positioning.

Well compatible with silicon‑based photodetectors, PLD905‑75W‑P is widely used for high‑power handheld laser rangefinders, long‑distance UAV ranging & obstacle avoidance and performance‑oriented civil LiDAR modules. Factory direct supply supports prototype sample testing and large‑volume orders.

Critical Limitation Notice：

This plastic‑molded package is non‑hermetic. It is intended for civil commercial indoor / protected outdoor equipment; not suitable for continuous salt‑fog or high‑humidity harsh environments. End‑products must comply with IEC 60825‑1 laser‑safety requirements for invisible infrared laser emission.

Core Design & Performance Benefits‑ Triple stacked‑emitter chip architecture：

‑ Triple stacked‑emitter chip architecture：Multi‑layer vertical stacked emitters deliver ultra‑high peak power under nanosecond short‑pulse drive without enlarging chip dimension, greatly enhancing signal strength for extended ranging performance.

‑ Predictable beam divergence characteristics：Clear fast‑axis / slow‑axis far‑field beam angles simplify secondary optical lens design for your long‑range ranging modules.

‑ Stable spectral output over temperature：Nominal 905 nm central wavelength with narrow spectral bandwidth. Low wavelength thermal drift minimizes system calibration workload across full operating temperature scope.

‑ Two lead‑frame material options for tiered products：Gold‑plated lead‑frame delivers superior anti‑oxidation performance for equipment with long service cycles; silver lead‑frame optimizes BOM expenditure for mass‑volume projects, optical performance remains consistent for two variants.

‑ Standard through‑hole plastic housing：Common pin definition supports simple PCB soldering and high‑volume automated assembly;‑40 °C ~ +85 °C wide temperature range covers most civil sensing working environments.

‑ 100% batch optical‑electrical pulsed testing：Each production batch is validated under real pulsed operating condition, ensuring stable power output and beam uniformity, reducing early‑failure probability for finished sensing modules.

Key Operating Parameters

Standard Test Reference：100 ns pulse width,3 kHz repetition rate,TA = 25 °C

Real‑World Application Scenarios

Designed for Time‑of‑Flight optical ranging projects requiring higher peak power, mass manufacturability and controlled component cost：

‑ High‑power Handheld Laser Rangefinder(LRF): long‑distance golf & hunting rangefinder, civil engineering survey instruments

‑ UAV payload: long‑range drone altimetry, ranging and obstacle‑avoidance sensing

‑ High‑performance civil LiDAR and robot long‑distance detection modules‑ Industrial non‑contact long‑range measuring sensors

What Makes Leirte Different

1. Dual lead‑frame stock options：one part number covers two lead‑frame material choices, helping you optimize BOM cost according to product tiers.

2. Sample‑friendly procurement：small‑quantity samples available for lab prototype validation before mass commitment.

3. Photonics engineering support：we provide test‑condition guidance, characteristic curve references and integration suggestions for your drive‑circuit & optical‑path design.

4. Controlled batch consistency：rigorous pulsed‑mode production screening reduces variance when scaling to mass production.
