Widest Range of Wavelengths
The New Focus Velocity is available at wavelengths from the UV to the mid-IR.
Linewidth: Heterodyne Beat Note Method
Historically, linewidth is measured over an integration time of 50 msec or longer with the heterodyne beat note method utilizing two independent similar ECDLs. This method is less dependent on the measurement setup and provides a true snap shot of spectral broadening.

Linewidth: Delayed Self-beat Note Method
The delayed self-beat note method is another linewidth measurement technique. While this technique filters out spectral broadening, it provides an instantaneous snapshot of the Lorentzian spectrum. The New Focus Velocity laser measures 2.5 kHz over a delayed 4.6 µs measurement.

Compatible Power Sensors
To verify and analyze the output power of your Velocity laser, we recommend the Ophir PD300 (7Z02410), PD300-IR (7Z02412) or 3A (7Z02621) 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 Velocity, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
