    OFM-12-DP 12-Channel Optical Delay Phase Modulator

    Precisely matching optical path lengths and phase, with loading up to 12 independent channels

    OFM-12-DP 12-channel optical delay phase modulator is designed to precisely match optical path lengths and modulate the phase of multiple laser channels. It effectively solves the problem of phase matching and reduced coherence length in high-power, narrow-linewidth lasers caused by spectral broadening. The OFM-12-DP optical delay phase modulator integrates 12 independent channels, each with its own optical delay line and electro-optic phase modulator, allowing for a wide range of delay adjustments and high-precision phase control.

    Features
    • Dual-Mode Modulation Technology
      Delay modulation: Supports picosecond (ps) to nanosecond (ns) laser pulse delay adjustments with sub-picosecond resolution, ideal for applications requiring strict timing synchronization (e.g., quantum entanglement experiments).
      Phase modulation: Offers a modulation rate of 100MHz and highly linear phase control, enabling dynamic beam wavefront shaping or light field coherence optimization.
    • Array Integration Design
      Integrates 12 independent modulation channels, supporting synchronous or asynchronous control of multiple lasers to reduce system size and complexity.
      Utilizes a Lithium Niobate (LiNbO₃) material process to ensure low insertion loss (<3 dB) and high stability.
    • Smart Control Interface
      Supports dual-mode operation via electronic control or software programming, compatible with external control modules like FPGAs and DSPs for real-time dynamic adjustments.
      Provides an API for seamless integration into automated optical experimental platforms or industrial equipment.
    Applications
    • Coherent synthesis
      For matching optical path differences and phase control in laser array optical paths.
    • Laser phased arrays
      For dynamic beam shaping and atmospheric turbulence compensation of laser arrays.
    • Lidar
      Enables timing synchronization and beamforming for multi-beam scanning.
    • Fiber sensing
      Enhances distributed acoustic/temperature sensing performance through phase detection technology.
    Advantages
    • High precision
      Features all-temperature-range (-40°C to 85°C) phase drift compensation technology, ensuring long-term stability.
    • Scalability
      Supports cascading of modules to expand to 24 or 48-channel arrays, adapting to the needs of large-scale laser array coherent control.

    With its multi-channel, high-precision, and strong compatibility, the OFM-12-DP optical delay phase modulator is a core component for both cutting-edge optical research and industrial-grade laser systems.

    Our tunable narrow linewidth laser seed source integrates a single-frequency PM fiber laser, a wide-bandwidth electro-optic phase modulator, and a driver circuit. By applying a specific RF signal to the single-frequency seed light via the modulator, the spectral width is successfully expanded from kHz to the 100GHz range, effectively suppressing the SBS effect that can occur during high-power amplification and thereby increasing the output power.

    Our 4-channel narrow linewidth low-noise pm fiber amplifier array is a core component of our next-generation low-noise fiber amplifier systems. It features an integrated opto-electro-mechanical design with four independent high-performance PM fiber amplifier channels. This module offers exceptional amplification with a total power of 80W. The standard version operates stably across a wide temperature range of -5°C to +45°C, and a military-grade reinforced design is available for extreme environments.

    CP Laser's multi-node data acquisition and interlock protection system is specifically designed to meet the complex challenges of data acquisition and safety interlocks in industrial environments. It supports up to 100 nodes, meeting the needs of large-scale industrial sites. When sensor data exceeds a preset threshold, the system automatically triggers an alarm signal, ensuring equipment and production safety.
