KHL-P2000 Laser Spot Heating System
Product Overview
The KHL-P2000 Laser Spot Heating System is a 2000-W high-power-density laser local thermal loading solution designed for high-temperature material research, extreme thermal environment simulation, material performance testing, and advanced manufacturing process development. Using a high-power semiconductor laser as the heat source, the system delivers precise energy to target areas via fiber-optic transmission, beam shaping, and focusing modules to achieve rapid heating, localized thermal treatment, and non-contact loading. Typically comprising a laser source, optical transmission/focusing module, temperature sensing module, and control system, it enables closed-loop temperature control through infrared thermometry or thermal imaging to meet precision thermal process requirements in both research and engineering applications.

Product Type
How it works
The system uses a high-power semiconductor laser as the heat source. Laser energy is delivered via fiber optic cable, shaped, and focused to precisely target specific areas for rapid heating, localized treatment, and non-contact thermal loading. The device supports two beam modes—flat-top and Gaussian—with customizable spot sizes ranging from 2 to 25 mm. Integrated with non-contact temperature measurement tools such as infrared thermometers and thermal cameras, it enables closed-loop temperature control with real-time laser power adjustment. Both continuous output and power modulation operating modes are supported.
The system comprises five modules: laser heat source, optical shaping, temperature sensing, control, and mechanical integration interfaces. The laser heat source module delivers stable 2000 W laser output. The optical shaping module manages beam transmission, focusing, and energy distribution control. The control module handles laser power adjustment, program execution, alarms, and safety interlocks. The mechanical integration interface supports installation on experimental platforms and automated systems. Compared to traditional furnace heating methods, this system offers faster thermal response, precise targeting, and a smaller heat-affected zone, meeting experimental requirements for materials under extreme temperature gradients and rapid thermal cycling conditions.
Important Notice:The typical temperature range is 1000～2000℃, depending on material absorptivity and operating conditions. Formal projects shall follow the agreed test conditions and acceptance criteria.

Usage and Safety Instructions
- ⚠Strong visible and infrared radiation is emitted during operation. Do not look directly at the light source or focus area. Use appropriate eye and radiation protection equipment.
- ⚠The sample, heating head tip, and surrounding structures may be hot. Install heat guards and allow adequate cooldown time after power-off.
- ⚠Keep the air-cooled channel clear. Do not operate continuously if cooling is abnormal, the reflector surface is contaminated, or electrical connections are loose.
- ⚠Infrared temperature readings are affected by emissivity, angle, and spot size coverage. For highly reflective metals, combine with thermocouples or use a calibrated measurement solution.
- ⚠For adhesives, coatings, and materials that may emit volatiles, evaluate ventilation, smoke extraction, and fire safety conditions.

Energy Distribution Diagram
Figure 3Gaussian Beam Energy Density Profile: Energy density follows a Gaussian distribution from the center outward, with peak intensity at the center gradually tapering toward the edges. The central region reaches high temperatures, making it ideal for localized melting and drilling applications with minimal heat-affected zones.
Figure 4Flat-top laser spot energy density map: Energy is uniformly distributed within the spot with a sharp drop-off at the edges. The uniform energy region is controllable, making it ideal for uniform heating, surface treatment, annealing, sintering, and other applications.
Note: The illustration shows a typical beam energy density distribution; actual distributions may vary slightly due to optical system and measurement conditions.
