Single-Wavelength Lasers

Product catalog summary

Overview: The SWL-7500 Series are single-wavelength lasers known for their exceptional wavelength and power stability, compact size, and rugged design. They are OEM-ready and suitable for various applications such as Raman imaging, spectroscopy, interferometry, terahertz generation, data encryption, fiber gyroscopes, and LIDAR.

Specifications: The lasers are available in factory-set wavelengths of 633, 660, 780, and 785 nm, with custom wavelengths available upon request. They offer a narrow linewidth of less than 200 kHz and maintain wavelength stability of less than 0.4 pm/°C. The lasers have a long operational lifetime of over 5000 hours and are designed to operate continuously on a single longitudinal mode with minimal frequency drift.

Performance: The SWL-7500 series provides high power stability (<2% p-p) and low background interference, ensuring a clean and unambiguous signal. The lasers feature a side mode suppression ratio of less than -50 dBc and amplified stimulated emission (ASE) of less than -65 dBc.

Design and Dimensions: The free-space head dimensions are 2.5" × 1.25" × 1.25", while the fiber-coupled head dimensions are 4.75" × 3.4" × 2.00". The controller dimensions are 5.67" × 6.00" × 1.94". The lasers operate within a temperature range of +5 °C to +50 °C and can be stored between -20 °C and +60 °C.

Fiber-Coupled Models: The SWL-7500 series also offers fiber-coupled models with high coupling efficiency and excellent beam quality. These models are available with single mode (SM) or polarization maintaining (PM) fibers and provide over 35 dB isolation to ensure continuous single-mode performance.

Controller Features: The dedicated controller for the SWL-7500 series is compact and provides low-noise current to the diode, maintaining precise temperature control. It includes RS-232 communications and a GUI interface for easy remote control and integration.

Safety and Compliance: The SWL-7500 lasers are classified as Class IIIb laser products and comply with 21 CFR 1040.10 and 1040.11 regulations, with specific deviations as per Laser Notice No. 50.
