High-Power Single-Frequency Tunable Laser

The USL Series High-Power Single-Frequency Tunable Lasers deliver high output power and an ultra-narrow linewidth in a compact single-frequency fiber-laser platform. A DFB seed, all-fiber amplification chain, and frequency-doubling via periodically-poled crystals enable multi-wavelength, high-power single-frequency output. Key features include relative-intensity noise of −140 dBc/Hz at 100 kHz, no mode-hopping over wide temperature and vibration ranges, outstanding beam quality (M² < 1.2), and an integrated seed shut-down protection system. The rugged opto-mechatronic design is easy to relocate and operate, making the USL series ideal for spectroscopy, interferometry, LiDAR, optical communications, and more.

Key Advantages:

High power, ultra-narrow linewidth
Excellent power stability
Precise wavelength tuning
Low intensity noise
Superior beam quality
Seed shut-down protection

Applications:

Spectroscopic sensing
