Overview

Unlocking NIR Femtosecond Potential: Compact Engine for THz and Precision Metrology

The ErFemto-780 Elite Series utilizes automatic mode-locking and low-noise fiber amplification technology, converting 1560nm fundamental light into 780nm femtosecond pulses via a high-efficiency frequency doubling module.

Achieving miniaturized optoelectronic design, it ensures ultrashort pulses of <100fs through high-precision dispersion compensation, making it an ideal alternative to complex solid-state lasers as a seed source or standalone light source.

Applications

THz Time-Domain Spectroscopy
Laser Ranging
Micro-nano 3D Printing
Seed Source for Fiber/Solid-State Lasers

Interfaces & Operation Environmental Requirements

Equipped with RS232 interface for remote PC control. Operating Temperature: 18 - 32 ℃.
Provides TTL synchronization output port for easy syncing with detection equipment.
