Footnotes:

  1. Due to our continuous product improvement program, specifications are subject to change without notice.
  2. Motorized wide tuning and PZT fine tuning. Contact us for other available wavelengths and typical tuning curves. Wide tuning is mode-hope-free in constant current mode only.
  3. Resolution is 10 mV in PZT (0.01% of full PZT tuning range) through controller front panel or command interface. When tuning PZT using an external voltage source through External Frequency Modulation input, resolution is dependent on voltage source.
  4. Current modulation directly to diode through laser head SMA port.
  5. Free space (with and without isolator) output is vertically linearly polarized with respect to laser head base.
  6. Optically-isolated option includes an integrated 35 dB optical isolator for free-space output with approximately 75% power transmission. Fiber-coupled option includes isolator and permanently fixed Panda-type PM fiber with FC/APC connector for laser output. Wide-type alignment key aligned with the slow axis of the PM fiber. Dual stage isolation, other fiber types and connectors available upon request. Optically-isolated option for TLB-6732 available upon request. Fiber coupled option for TLB-6732, TLB-6736, and TLB-6740 available upon request.

Features

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.

Heterodyne beat note of two Velocity TLB-6712 lasers, 50 ms integration. Deconvoluted linewidth <200kHz

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.

Delayed (4.6 µs) self-homodyne linewidth 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.
