HQF Series Lamp-pumped Picosecond Laser

Introduction to HQF Series Lamp-Pumped Picosecond Lasers (RealLight)
With years of in-depth research and development in the laser industry, Beijing RealLight Technology Co., Ltd. has launched the HQF series lamp-pumped MOPA picosecond lasers relying on independent core technologies and complete production systems. As high-energy solid-state picosecond laser equipment, this product features advanced optical path design, superior optical performance and outstanding operational stability. It is applicable to diversified scenarios including scientific research and biomedicine, serving as a cost-effective and highly reliable laser product for both commercial and research purposes.


Product Structure & Design Concept
Adopting a classic single-lamp dual-rod amplification structure, the HQF series laser system consists of three core modules: self-developed MC series microchip laser, RL-ISO series optical isolator and lamp-pumped laser amplifier. The optical path is compact and reasonably arranged. The whole machine adopts sealed protection treatment to effectively isolate dust, moisture and other external interferences, improving environmental adaptability and service life of the equipment. In addition, modular optional configurations are available, including built-in optical shutter and energy detector. Supporting accessories such as articulated arm, control screen, dedicated power supply and water chiller can also be matched optionally, enabling rapid integration into various laser systems to meet customized application demands.


Core Performance & Technical Advantages
Highlighting three core strengths of high pulse energy, narrow pulse width and excellent stability, this laser series delivers competitive overall performance meeting mainstream industrial standards:

1. Ultra-high Pulse Energy & Peak Power
The laser covers two common wavelengths: 1064nm (fundamental wavelength) and 532nm (frequency-doubled wavelength), with a maximum peak power up to 1.5GW for the whole series. Two customized models are available for different application demands. The high-energy version delivers single pulse energy of 500mJ at 1064nm and 250mJ at 532nm, while the standard version provides 400mJ at 1064nm and 200mJ at 532nm. The high-power output perfectly supports high-demand applications such as tissue ablation, spectral detection and long-distance laser detection.

2. Narrow Pulse Width & Superior Beam Quality
The two models are designed with differentiated pulse widths: 350ps for the high-energy version and 400ps for the standard version. Both belong to standard picosecond laser output with extremely low thermal damage. Equipped with flat-top beam mode universally, the laser features a beam diameter of approximately 11mm with outstanding beam uniformity. The full-angle divergence angle at 1/e² is less than 3mrad in both horizontal and vertical directions, ensuring consistent laser output and avoiding extra damage caused by partial over-energy. The vertical polarization direction is compatible with most mainstream optical systems, making it ideal for medical aesthetic scenarios with strict requirements on beam uniformity.

3. Stable Laser Output Performance
The laser boasts excellent energy stability. For the high-energy version, the root mean square (RMS) energy stability is less than 2% at 1064nm and less than 3% at 532nm; for the standard version, the RMS energy stability is less than 3% at 1064nm and less than 4% at 532nm, ensuring negligible output fluctuation during long-term continuous operation. The repetition rate is continuously adjustable from 1Hz to 10Hz to fit diverse working conditions. The total power consumption is lower than 500W, realizing low operating cost and energy-saving operation.

4. Strong Compatibility & Easy Deployment and Maintenance
The power supply supports wide-range AC input of 110V/220V±10% with compatibility for both 50Hz and 60Hz power grids, adapting to global mainstream power supply standards. The equipment has low requirements for operating environments: the applicable working temperature ranges from 10℃ to 30℃, and the relative humidity should be kept below 75%. It can be directly deployed in conventional laboratories, industrial workshops and medical aesthetic rooms without complex transformation of constant temperature and humidity sites, greatly reducing site construction and operation maintenance costs.


Detailed Technical Parameters
The HQF series lamp-pumped picosecond lasers are divided into two models with graded optical parameters to match different budgets and application scenarios. Both models support dual-wavelength output of 1064nm and 532nm, with the repetition rate adjustable within 1Hz to 10Hz. In terms of pulse width, the high-energy model outputs 350ps pulses while the standard model outputs 400ps pulses. All beam parameters are identical for the two versions, including a beam diameter of around 11mm, universal flat-top beam mode, full-angle divergence angle below 3mrad in both horizontal and vertical directions, and fixed vertical polarization. All electrical and environmental parameters are unified across the series. Featuring wide-voltage power supply and power consumption below 500W, the laser can be quickly integrated and put into use without additional site renovation.


Diversified Application Fields
Benefiting from dual-wavelength output, high pulse energy and uniform flat-top beam, the HQF series lasers are widely applied in biomedicine, industrial measurement and scientific research:

1. Biomedicine (Core Application)
Serving as the core light source for medical aesthetic laser devices, it is widely used in tattoo removal, freckle removal, chloasma removal, skin rejuvenation, epidermal nevus removal and acne treatment. The picosecond narrow pulse width enables precise targeting on lesion tissues while minimizing thermal damage to surrounding normal skin tissues, ensuring safer and more effective clinical treatment. Besides, it is also applicable to clinical research including biological tissue ablation.

2. Industrial Detection & Measurement
It can be deployed for laser ranging, differential absorption lidar, particle image velocimetry, laser ultrasonic measurement and other industrial testing applications. Its high-energy laser output guarantees high-precision long-distance detection, and stable beam output effectively improves the accuracy of measured data.

3. Scientific Research
The laser is an ideal experimental light source for universities and research institutes, covering cutting-edge optical research directions such as laser-induced breakdown spectroscopy, laser-induced fluorescence and nonlinear optics. Its narrow pulse width and ultra-high peak power fully meet the stringent optical parameter requirements of advanced optical experiments and material analysis research.
