This product series is designed to provide outstanding light source solutions for demanding application fields such as industrial processing, scientific research, and medical device manufacturing, breaking through the performance bottlenecks of traditional laser technologies.
OL(S) Series 50 Core Technology Highlights
The OL(S) Series 50 lasers integrate innovative technologies to ensure stable, reliable, and efficient laser output under various complex working conditions.
- Revolutionary Micro-Channel Cooling Technology
- Technical Principle: By integrating precisely designed micro-channels directly beneath the laser bars, the cooling medium (such as deionized water) can get closer to the heat source, achieving extremely high heat exchange efficiency.
- Customer Value:
- Superior Thermal Performance: Effectively manages the immense heat generated at high power densities, ensuring stable laser junction temperatures, thereby significantly enhancing the laser’s output power and operational stability.
- Extended Operational Lifetime: Excellent temperature control capability drastically reduces the aging rate of semiconductor materials, enabling the OL(S) Series to achieve an expected lifetime of up to 10,000 hours in Continuous Wave (CW) mode and 1 billion pulses in Quasi-Continuous Wave (QCW) mode.
- Improved Beam Quality and Wavelength Stability: Stable operating temperatures help maintain better beam quality and a narrower spectral width (typically <3nm), with a low wavelength temperature coefficient of approximately 0.28 nm/°C.
- Enables Higher Power Density: The compact cooling structure makes it possible to integrate more laser bars within a limited space, increasing the overall module’s power density.
- Powerful Output and Flexible Operating Modes
- Power Range:
- Continuous Wave (CW) Mode: Single modules can provide stable optical power output up to 960W, 1440W, 2000W, and even 3000W.
- Quasi-Continuous Wave (QCW) Mode: Peak power covers 2.4KW, 4.8KW, 10KW, and can be configured up to 25KW according to demand, supporting high duty cycles up to 60% (depending on the specific model).
- Customer Value:
- Broad Application Versatility: Whether for long-duration processing requiring continuous stable energy output or pulsed applications needing high peak power, the OL(S) Series offers ideal solutions.
- Efficient Energy Conversion: The slope efficiency per bar is greater than 1.15 W/A, signifying higher electro-optical conversion efficiency, which helps reduce system energy consumption.
- Power Range:
- Robust and Durable Fully Sealed Structure
- Design Philosophy: The core optical path and electronic components inside the laser are fully sealed, effectively isolating them from external contaminants such as dust and moisture.
- Customer Value:
- Enhanced Environmental Tolerance: Ensures reliable laser operation even in non-ideal clean or humid industrial environments, reducing failures caused by environmental factors.
- Reduced Maintenance Costs: The sealed design lessens the need for cleaning internal optical components, extending maintenance intervals.
- Prevents Condensation Risk: In systems requiring active water cooling, it effectively prevents condensation on critical internal parts, ensuring operational safety.
- High-Density Bar Integration and High Power per Bar
- Core Configuration: A single OL(S) module can vertically integrate up to 64 laser bars (standard configurations are 24 or 50 bars; other quantities customizable), with single bar output power up to 500W.
- Customer Value:
- Ultimate Output Capability: Through the combination of multi-bar stacking and high power per bar, a single module can achieve astounding outputs of up to several kilowatts (CW) to tens of kilowatts (QCW).
- Compact Design: While ensuring total power, the overall module size is optimized, facilitating integration into space-constrained systems.
- Flexible Customization Services
- Customization Scope: In addition to the number of bars, we offer customization of the central wavelength (standard 808nm±3nm, optional “rainbow” wavelength combinations from 792nm to 814nm), structural design (such as OL(S)-24 and OL(S)-50 structures), and more.
- Customer Value:
- Precisely Matches Application Requirements: We understand that different applications have unique demands for laser parameters. Through customization services, we ensure the laser you receive perfectly fits your system.
- Optimized System Integration: Customized structural and interface designs allow the OL(S) Series to be more conveniently integrated into your existing or new equipment.
