The SWL-7500 Single Wavelength Diode Laser is a robust, narrow linewidth, laser source offering single longitudinal mode performance at a fixed wavelength. Their rugged build and tiny footprint make them ideal for OEM integration for imaging, metrology, or spectroscopic measurements.
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.
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.
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.
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.
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.
