1550nm High power pulsed light source

The product is developed by the company's high-stability pulsed laser light source. The core device uses a highly stable laser, unique APC (automatic power control) and ATC (automatic temperature control) circuit,ensuring high output power and wavelength ; using high stability and high precision MPU (microprocessor) system ,making it easy and reliable to display.

Features:
  • Stable laser output is stable
  • Nanosecond pulse output
  • Large peak power
  • Single-mode fiber output
  • Pulse width, repetition frequency, light pulse power are adjustable
  • Small volume
Applications:
  • Distributed optical fiber sensing system
  • Coherent optical communication
  • Scientific research
