Overview
JPT LARK-355-5A & Lark-355-5ASE Air-Cooled UV Laser Sources
The JPT LARK-355-5A and Lark-355-5ASE are 5 W-class, air-cooled UV laser sources designed for precision marking and industrial micromachining. Both models operate at 355 nm and deliver more than 5 W of average output power at 50 kHz, with short pulse duration, high beam quality and low thermal impact on sensitive materials.
The LARK-355-5A is the earlier model, while the Lark-355-5ASE is the newer-generation option. They support the same core marking functions and comparable processing results, but use different internal component configurations. The 5ASE also features a newer, compact air-cooled platform for straightforward OEM and marking-system integration.
Best For
- Fine marking on plastics, glass, ceramics and electronic components.
- Precision processing of semiconductors and heat-sensitive materials.
- High-quality drilling, cutting, scribing and micro-pattern processing.
- OEM marking systems requiring a compact UV source without a water chiller.
Key Features
- 355 nm UV Wavelength: Creates a small focused spot with a limited heat-affected zone.
- More Than 5 W Output: Rated above 5 W at 50 kHz for precision industrial processing.
- Air-Cooled Operation: No external water-circulation cooling system is required.
- New and Legacy Options: Select the newer 5ASE platform or the established 5A model.
- Comparable Processing Capability: Both models are intended for the same core functions and process results, with different internal components.
- High Beam Quality: M² ≤ 1.2 with greater than 90% beam circularity.
- Flexible Integration: 12 V DC input, GUI monitoring, and internal or external control modes.

Choosing Between 5A and 5ASE
- Choose Lark-355-5ASE for the newer-generation platform and lower net weight.
- Choose LARK-355-5A when an existing machine design or replacement requirement specifies the earlier model.
- Both models are designed for comparable core functions and process results; internal components and physical dimensions differ.
Safety & Integration Notes
- These are Class 4 laser products and must be integrated and operated by trained personnel in a controlled laser work area.
- Wear laser safety eyewear suitable for 355-1064 nm and prevent exposure to direct, reflected or scattered radiation.
- Confirm the model, power supply, grounding, signal connections and cooling airflow before installation.
- Do not disassemble the laser. Maintenance and servicing should be performed by authorized technical personnel.
FAQ
What is the difference between LARK-355-5A and Lark-355-5ASE?
The 5A is the earlier model and the 5ASE is the newer model. They are designed for the same core functions and comparable processing results, but their internal component configurations, dimensions and weights differ.
Is the Lark-355-5ASE air-cooled?
Yes. The Lark-355-5ASE uses integrated air cooling and does not require an external water chiller.
Which model should I choose?
Choose the 5ASE for the newer platform. Choose the 5A when matching an existing installation or replacement specification. Sample testing is recommended before final selection.
5A: 500 × 200 × 250 mm; 5ASE: 450 × 200 × 250 mm
