Features

Exceptional Wavelength and Power Stability

The user-selected single, fixed wavelength of the SWL-7500 laser is stabilized using internal optics and precision temperature control. Additionally, the laser output power is controlled by an ultra-low-noise current source. All this results in exceptional wavelength and power stability.

Highly stable cavity design yields extremely low wavelength drift. - No signal drift - High precision without calibration

High Power and Extremely Narrow Linewidth for Raman Spectroscopy

With powers up to 150 mW at 785 nm and a linewidth <200 kHz measured over 50 ms, the SWL-7500 lasers are ideal for precision Raman spectroscopy applications.

All Solid-State, Tiny Footprint, OEM Ready

With a footprint that is smaller than a business card, the laser will fit in most instrument designs with room to spare. We have carefully designed these lasers to operate continuously on a single longitudinal mode and minimal frequency drift as the heart of any imaging, metrology, or spectroscopic measurements. Long-term wavelength and power stability make this laser a miniature work horse.

Integrated Permanent Fiber-Coupling

The fiber-coupled versions feature an integrated optical isolator and a permanently fixed and aligned fiber, eliminating fiber misalignment to increase efficiency and maintain power stability.

SWL-7500 OEM-Grade Controller

The OEM controller features low current noise, a high-capacity TEC controller, a RS-232 interface with GUI or binary control, and CE & RoHS compliance.
