1550nm Nanosecond Pulsed Erbium Fiber Laser for Free Space Communication
Techwin 1.5µm Nanosecond Pulsed Erbium Doped Fiber with Broadband Linewidth (<1nm) and Ultra Low Phase Noise, Ultra Low Relative Intensity Noise (RIN) 1550nm Fiber Laser Source for Free Space Communication
The nanosecond pulsed fiber laser is commonly designed with master oscillator power amplifier (MOPA) architecture. The master oscillator generates initial pulses at ns level. After pulse shaping, the single-stage or multi-stage power amplifier boosts the pulse supplied by the oscillator to achieve high power output.
The nanosecond pulsed fiber laser is a high power pulsed laser source based on the wavelength which is safe to human eyes. It adopts high performance narrow linewidth distributed feedback (DFB) semiconductor laser as seed source, and built-in signal generator. The multi-stage optical amplification is optimized to achieve high peak power laser output with ns level pulse width. This nanosecond pulsed fiber laser is suitable for distributed temperature sensing (DTS) system, fiber optic sensing, LiDAR and other applications in various industries.
These lasers are powered via 5-12V DC power supply, designed with industrial standard DB25 communication port. Besides, the pulse output can also be achieved by external TTL signal, suited for system integration.
Free-space Optical Communication (FSO) is an fiber optical communication technology that uses fiber laser light propagating in free space to wirelessly transmit data for telecommunications or computer networking. ”Free space” means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable.
The technology is useful where the physical connections are impractical due to high costs or other considerations.
