HQF Series Lamp-pumped Picosecond Laser with Built-in Energy Detector

RealShock® HQF Series Lamp-Pumped Picosecond Laser with Built-in Energy Detector Product Introduction
RealLight Technology launches the RealShock® HQF Series Lamp-Pumped Picosecond Laser with Built-in Energy Detector, a high-energy solid-state picosecond laser source adopting a dual-lamp dual-rod amplification architecture. The complete system integrates self-developed MC series microchip seed laser, RL-ISO optical isolator and high-power lamp-pumped amplification module. Equipped with a factory-fitted built-in optical shutter and real-time energy detector, it eliminates the need for additional external testing equipment. Balancing integration level, stability and operational safety, this domestically-manufactured high-energy picosecond laser solution serves biomedicine, precision detection, spectral scientific research and many other scenarios.

1. Overall Structure & Core Design Highlights
This laser adopts a dual-lamp dual-rod optical amplification layout. Compared with single-lamp schemes, it delivers higher maximum pulse energy output, more balanced heat distribution and lower performance attenuation during long-term continuous operation. The entire optical path is hermetically sealed to isolate interference from dust, moisture and temperature fluctuations, greatly extending the service life of optical components.

The product’s most distinctive advantage lies in the integrated combination of built-in energy detector and safety optical shutter. The energy detector captures real-time pulse output energy and transmits feedback data to the matched control screen, enabling operators to monitor and calibrate output parameters on the spot. It perfectly fits high-standard scenarios including standardized aesthetic treatment and quantitative scientific experiments. The built-in optical shutter rapidly cuts off laser output to avoid accidental light emission risks and raise overall operational safety.

A full range of optional supporting components is available, including medical articulated arms, touch control panels, dedicated drive power supplies and recirculating water chillers. The modular structure allows rapid integration into aesthetic equipment, scientific test platforms and industrial inspection instruments for easy on-site deployment.

2. Core Performance Advantages
1. Ultra-high Single Pulse Energy & Peak Power
The laser provides dual-wavelength output at 1064nm fundamental frequency and 532nm frequency-doubled band. The maximum single pulse energy reaches 500mJ at 1064nm and 250mJ at 532nm, with a peak power up to 1.5GW. The repetition rate is continuously adjustable from 1Hz to 10Hz to switch pulse emission frequency according to treatment and experimental demands. Its high-energy output is ideal for tissue ablation, long-distance laser detection, spectral excitation and other working conditions.

2. 300ps Narrow Picosecond Pulse Width for Minimal Thermal Damage
The fixed pulse width (FWHM) of 300ps falls within standard picosecond range. Compared with traditional nanosecond lasers, it delivers a smaller thermal conduction range. In aesthetic applications, it accurately shatters pigment particles while reducing burns to surrounding normal skin. For scientific experiments, it achieves material interaction with negligible thermal damage to guarantee pure experimental data.

3. Uniform Flat-top Beam & Highly Stable Output
It features a flat-top beam profile with a beam diameter of approximately 11mm. The full-angle divergence angle at 1/e² in both horizontal and vertical directions is less than 3mrad, delivering outstanding beam uniformity without local over-energy hotspots. Energy stability is excellent: RMS fluctuation is less than 2% at 1064nm and less than 3% at 532nm, ensuring consistent output during long-hour operation for unified aesthetic treatment effects and highly repeatable scientific data. The laser features vertical polarization, compatible with most mainstream optical system docking standards.

4. Wide Power Compatibility & Loose Operating Environment Requirements
It supports 110V/220V ±10% AC mains power and adapts to global 50/60Hz power grids. The total power consumption is below 800W for controllable energy costs. The laser stably operates within an ambient temperature range of 18°C to 35°C with relative humidity below 75%. No strict constant temperature & humidity renovation is required for conventional aesthetic clinics, laboratories and industrial workshops, cutting overall deployment costs.

3. Full Technical Parameter Description
All models of the HQF Series picosecond laser with built-in energy detector support dual-wavelength output of 1064nm and 532nm, with repetition rate adjustable from 1Hz to 10Hz. The maximum pulse energy is 500mJ at 1064nm and 250mJ at 532nm; RMS energy stability is less than 2% for 1064nm and less than 3% for 532nm. The unified pulse width is 300ps. All beam parameters are consistent across the series: beam diameter around 11mm, flat-top beam distribution, full-angle divergence angle below 3mrad in horizontal and vertical directions, and vertical laser polarization.
