  1. Due to our continuous improvement, all specifications are subject to change without notice.
  2. After 30 minute warm up..
  3. SPFL 532 is a Class IV -- High Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to the direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.


High Power with Cutting Edge Technolog

Spectra Physics’ SPFL 532 series of pulsed green fiber lasers (532 nm) incorporate cutting edge technology to provide top performance for such precision-intensive applications as those required for solar cell manufacturing, micro machining, silicon scribing, fine processing, glass processing, thin film cutting and more.

The SPFL 532 lasers are comprised of linearly polarized Ytterbium fiber lasers in a smart and flexible MOPA configuration utilizing a second harmonic generation (SHG) module to provide an output power of up to 40 W with a near-diffraction-limited output beam in the green wavelength.

High Pulse Repetition Rates and High Peak Power

SPFL 532 lasers offer high pulse repetition rates (up to 2 MHz with PRF on-the-fly), tunable short pulse durations (down to 3 nsec) and high peak power to enable high system throughput for maximum process efficiency. Combined with its pulse-on-demand capabilities the SPFL 532 brings remarkable agility and flexibility to the most demanding of applications.

Designed for Reliable Industrial Operation

Enclosed in a robust yet compact assembly that meets industrial standards and fitted with metal armored fiber cable, the ultra-flexible SPFL 532 lasers deliver a compelling combination of quality, reliability and performance.

Compatible Power Sensors

To verify and analyze the output power of your SPFL 532 laser, we recommend the Ophir F80(120)A-CM-17 (7Z07103) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the ophiropt.com website.  Other Ophir sensors and meters may also be suitable for the SPFL 532, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
