FQCW266-600 High Power UV Laser
High-Power 266 nm Laser with 600 mW Output for Maximum Precision
The FQCW266-600 – a high-power UV laser, stands for exceptional stability, efficiency, and longevity in the UV range. With a central wavelength of 266 nm and an output power of 600 mW, this laser delivers outstanding performance for demanding applications in both industry and research.
Upgrade Capability
The FQCW266 – High Power UV Laser platform allows for flexible performance adjustments during refurbishment. As a result, the FQCW266-600 can be upgraded from 600 mW to the next higher power level of 1,200 mW.
This provides maximum investment security and adaptability to changing demands in both industry and research.
Longevity & Easy Maintenance
The integrated Automatic Crystal Shifter (ACS) optimally utilizes the conversion crystal – significantly increasing lifespan and extending the maintenance interval to up to 16,000 operating hours.
Thanks to the air-cooled aluminum housing, no water cooling circuit is required.
For operation, a purge at the exit window with CDA (Clean Dry Air) or nitrogen (N₂) is sufficient – no internal gas management is needed.
Smart Control & Connectivity
Control the FQCW266 laser as needed:
- Manually at the push of a button
- Software-controlled via our control interface
- Externally via RS232, USB, or Ethernet
Designed for Continuous Operation
The FQCW266 – High Power UV Laser Series is designed for 24/7 applications in industrial environments – ideal for OEM customers in semiconductor manufacturing or high-precision research applications.
With a typical warm-up time of just 30 minutes and an average power consumption of 200 W, it impresses with efficiency and reliability at low operating cost.
