DRS Daylight | CW-MHF™ Mid-IR Laser

The CW-MHF Mid-IR Laser delivers impressive performance with a linewidth of ≤ 5 MHz (over 100 ms), ensuring precise, stable operation. Thanks to its unique Mode-Hop-Free (MHF) tuning, it can cover a range of over 30 cm^-1 and even surpass 100 cm^-1 in some cases. Designed with a stable laser cavity, it minimizes acoustic interference, offering consistently high performance. The laser also features dual modulation options (PZT and current modulation) for flexible wavelength control, making it perfect for high-resolution spectroscopy and wavelength reference locking.

Features & Benefits:

• Wavelength availability: <4 to >11 µm
