Pulsed laser source FS series

femtosecondshort-pulsetriggered

Product Overview
The JPT FS Series femtosecond infrared fiber lasers deliver ultrashort pulses (<400 fs) with high single‑pulse energy (>40 μJ) for extremely high peak power and sub‑micrometric precision. Built on a full‑fiber CPA architecture for industrial stability and reliability, the series supports Burst Mode, programmable time‑shift modulation, Position Synchronized Output (PSO) and wide repetition‑rate tunability from single pulse up to 1–2 MHz depending on model.

Key Features

• Ultrashort pulses: pulse width <400 fs to minimize heat‑affected zone and enable high‑precision processing.
• High single‑pulse energy: >40 μJ (model dependent) for strong material interaction.
• Full‑fiber CPA design: excellent long‑term output stability suitable for industrial environments.
• Flexible control: Burst Mode (1–10 pulses), programmable modulation and PSO synchronization for process integration.
• Wide frequency range: adjustable repetition rates from 25 kHz up to 2 MHz (model dependent).
• Industrial reliability: modular mechanical/electronic design with protection and monitoring features.

Pulse & Cooling Options

• Burst: optional burst function, selectable 1–10 pulses.
• Pulse duration: <400 fs (FS‑20), <300 fs (FS‑60) depending on model.
• Cooling method: water cooling (operating reference 25 °C).

Applications

• Micromachining and precision material processing
• Semiconductor manufacturing and inspection
• Medical device processing and microfabrication
• Scientific research and advanced laboratory applications
• Laser marking, cutting and drilling in industrial production
