Active Q-Switch Medical Beauty Laser Power Supply — Stable Output Is The Core Strength Of Laser Equipment

Manufacturers developing Q-switched spot removal, tattoo removal and 755nm skin rejuvenation complete machines often struggle with these common power supply pain points: Unstable energy output causing inconsistent treatment performance across finished devices; frequent Q-switch timing failures leading to lamp burnout; ordinary industrial power supplies failing medical device registration standards; scattered internal wiring slowing mass assembly efficiency...

The root cause lies in the lack of dedicated active Q-switch power supplies for medical beauty use. LZY QAM Series Nd:YAG active Q-switch power supplies are specially developed for pigment laser medical devices, comprehensively solving three major challenges of complete machine stability, regulatory compliance and mass production.

Working Principle of Active Q-Switch

The active Q-switch medical beauty power supply serves as both the power source and timing control core of spot removal & tattoo removal lasers. It consists of two independent modules: a xenon lamp pumping power supply circuit and a dedicated Q-switch drive control circuit. It precisely controls the resonant cavity Q value via electrical signals to generate nanosecond high-peak laser pulses, which differentiates it from passive Q-switch solutions without electronic control and self-triggering.

Core advantage of active Q-switch: The power supply outputs independently controllable electrical signals to manually and accurately switch high/low Q values. Passive Q-switch relies on spontaneous crystal triggering with uncontrollable timing sequences.

Modular internal structure + EMI-shielded metal housing Tests prove it effectively eliminates unstable operation caused by electromagnetic interference.

Four core parameters

1. Precise Active Q Control For Uniform & Stable Machine Output

As the core power hub of medical equipment, it adopts an isolated potting Q-drive module with high-voltage pulse rising edge as low as 15ns. It supports automatic Q-switch delay scanning, eliminating repeated manual calibration by engineers.

The power supply stores independent voltage and QDelay delay parameters for three wavelengths: 1064nm / 532nm / 755nm. Under a 100μF capacitor configuration, the single-channel model delivers a maximum single-pulse energy of 45J, while the dual-channel model reaches up to 90J. The repetition frequency is continuously adjustable from 1Hz to 10Hz with highly consistent pulse energy output. This ensures uniform treatment performance of finished devices and reduces inconsistent feedback from end customers.
