As advanced manufacturing continues its rapid evolution, microfabrication requirements are pushing far beyond the limits of traditional nanosecond and long-pulse laser technologies. Industries such as displays, semiconductors, photovoltaics, and consumer electronics are shifting toward design rules defined by ultra-fine features, minimal thermal damage, and uncompromising edge quality. Within this landscape, picosecond UV lasers have emerged as one of the most critical tools enabling next-generation production.
Since the company began volume shipments of picosecond lasers in 2019, independent industry data shows that Han’s Laser has captured more than half of China’s domestic picosecond laser market over the last three years. Thousands of units running 24/7 in demanding industrial environments have validated the platform’s long-term reliability and performance consistency.
Building on this foundation, Han’s Laser introduces the HL-PS-355-30, a 30W UV picosecond laser engineered to pair industrial durability with exceptional processing capability. It is designed for manufacturers seeking tighter tolerances, cleaner edges, and higher throughput—without sacrificing stability or cost efficiency.
Why Picosecond UV Technology Matters for Modern Microfabrication
Picosecond lasers sit in the “ultrafast” category, delivering pulses short enough to significantly reduce heat diffusion while still offering high pulse energy and efficiency. When combined with a 355 nm ultraviolet wavelength, the system benefits from:
- Low heat-affected zones (HAZ)
- Minimal taper and recast
- Superior absorption in metals, dielectrics, ceramics, and polymers
- High contrast and high-resolution structuring
These attributes make UV picosecond systems ideal for machining brittle and transparent materials, ultra-hard substrates, and multilayer flexible circuits—application spaces where nanosecond UV or infrared ultrafast lasers struggle to deliver consistent results.
An Industrial Picosecond Platform Built on the DRACO Architecture
The HL-PS-355-30 is developed from Han’s Laser’s well-established DRACO picosecond platform, optimized for high stability, high power, and cost-effective integration. The system was validated through field tests with tier-one customers and offers flexible customization options for specialized process needs.

Production-Level Quality Assurance and Reliability
To guarantee long-term stability, every 30W UV picosecond unit undergoes rigorous quality assurance integrated throughout the manufacturing process. Han’s Laser employs MES-based process tracking, and each unit must pass:
- Aging and long-duration stability tests
- Mechanical vibration and robustness tests
- Real-world process simulations under full power
These tests ensure that the laser maintains stable output power, beam quality, and pulse characteristics even under 24/7 industrial production cycles.
