PQE Series High Energy Solid-state Laser

RealShock® PQE Series High-Energy OEM Solid-State Laser Product Introduction
RealLight Technology independently develops the RealShock® PQE Series Diode-Pumped Passively Q-Switched Solid-State Laser, specially developed for precision analytical applications including Laser-Induced Breakdown Spectroscopy (LIBS), laser ablation and optical damage threshold testing. Adopting an integrated microchip optical path combining pump module and laser crystal, it delivers single pulse energy over 10 mJ with pulse width controlled within 3 ns. Featuring ultra-compact size, air cooling without water chiller and low power consumption, it is equipped with miniaturized OEM dedicated control circuit boards for mass integration into handheld portable detectors and field online inspection instruments, serving as a cost-effective domestic high-energy miniature pulsed laser source.

1. Integrated Micro Optical Path & OEM-Oriented Integration Design
The PQE Series adopts a microchip resonant cavity integrating diode pump module and laser crystal. Without complicated discrete optical components, the laser head is minimized to only 83×30×22.1 mm, easy to embed inside handheld probes and portable inspection devices. Equipped with pure air cooling instead of water cooling systems, it eliminates supporting chillers, water pipes and refrigeration units, simplifying system setup and reducing overall volume and supporting costs.
To meet secondary development demands of equipment manufacturers, an independent compact control circuit board (45×39.6×110.3 mm) is provided for flexible layout inside equipment cabinets. The circuit supports 12 VDC low-voltage power supply with maximum system power consumption of merely 20 W, compatible with battery-powered portable devices. It integrates RS-232 serial port and multi-channel I/O control interfaces, supporting both internal and external trigger modes for seamless connection with main control microcontrollers, spectral acquisition systems and timing synchronization modules, lowering debugging and integration barriers for mass production.
The laser features wide environmental adaptability: operating temperature ranges from 10°C to 35°C, while storage temperature withstands -20°C to 60°C, ensuring stable performance in field outdoor, vehicle-mounted and laboratory working conditions with no optical path drift during long-term operation.

2. Core Performance Advantages
2.1 Over 10 mJ High Single Pulse Energy in Miniature Form Factor for Ultra-High Peak Power
The standard model PQE-1064-0.01-10 emits 1064 nm infrared laser with single pulse energy exceeding 10 mJ and narrow pulse width below 3 ns, generating ultra-high peak power. It efficiently ionizes various metals, ores and soil samples to produce plasma for LIBS elemental analysis and laser ablation sampling, eliminating the need for extra energy amplifiers and simplifying overall optical architecture.

2.2 Stable Output for Repeatable Test Data
RMS energy fluctuation is less than 3%, delivering consistent pulse energy during long-duration continuous sampling to guarantee repeatable results for spectral detection and damage threshold testing. The full-angle divergence angle at 1/e² is 3 mrad in both horizontal and vertical directions, offering excellent beam convergence and precise focusing to minimize experimental errors.
2.3 Air-Cooled Low Power Consumption, Ideal for Lightweight Handheld Equipment
Abandoning water cooling systems typical of traditional high-energy lasers, the all-air-cooled design consumes maximum 20 W power and supports battery-driven handheld devices. The miniaturized lightweight laser head reduces the overall weight of handheld equipment for convenient field inspection operations.

2.4 Cost-Effective Standard OEM Solution
All core microchip optical components are self-produced with stable supply chains and prominent cost advantages for bulk orders. The standardized split laser head & control board scheme enables direct integration without complex optical adjustment, shortening equipment development cycles and acting as an economical alternative to imported miniature high-energy Q-switched lasers.

4. Key Application Fields
4.1 Laser-Induced Breakdown Spectroscopy (LIBS) Elemental Analysis
As the core excitation light source for handheld/portable LIBS analyzers, its ultra-high single pulse energy rapidly ionizes all types of solid samples for on-site rapid elemental identification of ores, alloys, soil and hazardous waste. The miniature size fits handheld probes perfectly, and air cooling enables continuous long-duration field sampling with stable energy to ensure accurate detection results.

4.2 Laser Ablation Sampling
Applied to micro-area material ablation and trace sample stripping. The narrow pulse width delivers an ultra-small heat-affected zone for precise ablation control, suitable for laboratory and online detection scenarios such as mass spectrometry coupling and surface composition analysis of materials.

4.3 Optical Damage Threshold Testing
Used for anti-laser damage performance calibration of optical films, lenses and crystal components. Stable and controllable pulse energy output enables accurate measurement of component damage thresholds, meeting quality inspection demands of optical laboratories and optical element manufacturers.

5. Product Summary
Built on RealLight’s self-developed integrated microchip passively Q-switched optical path, the RealShock® PQE Series High-Energy OEM Solid-State Laser achieves over 10 mJ high-energy pulse output within an ultra-compact housing, combining five core strengths: sub-3 ns narrow pulse width, air cooling without water chiller, low power consumption, portable compatibility and standardized OEM supporting components. The split laser head + control board architecture greatly lowers equipment integration barriers, suitable for mass development of handheld LIBS analyzers, field laser detection equipment and optical testing instruments.
