Haoliang Optoelectronic Provider Special/Polarization Controller. Has a high market share in the domestic market.

Typical regeneration amplification device diagram:

figure1A: :Linear structure, with two pulses passing through the modulator. This configuration only requires a quarter wave voltage to inject and extract pulses. Light separates the input and output beam paths.

figure1B::The circular structure only passes through the modulator once and requires the application of a half wave voltage, eliminating the need for an optical isolator.

Haoliang Optoelectronics can provide regenerative amplifier modulators and regenerative amplifier driver control modules.

If the instantaneous pump profile of the gain medium has a significant gain in the cavity for a considerable period of time before the injection of the pulse to be amplified, and immediately begins to increase after the extraction of the amplified pulse, then the gain medium is considered a continuous wave. Provide drivers for continuous wave pump and non continuous wave pump amplifiers.

Figure 2A:Figure 2A shows the waveform types that must be used with a continuous wave pump amplifier.Due to the presence of gain before the event occurs, the resonant cavity must remain open except during pulse cycles. The Model 25D driver and Model 307 (regenerative amplifier driver control module) are DC coupled and can freely choose the duration (cycle time) and number of cycles.

Figure 2B: Figure 2B shows the waveform when the intracavity gain is amplified and controllable in time. Because there was no gain before, there was no need to keep the cavity open and allow for dual pulse pickup. Haoliang Optoelectronics provides special customized implementation of dual pulse control driver combination.
