- Modern, low-noise design
- Easy-to-use controls and GPIB/RS-232 interfaces
- Half the size and weight of previous controller
- Backward compatible with Velocity lasers in the field
Our new low-noise Velocity tunable laser controllers are the state-of-the-art laser controllers for our most versatile laser series. And, with a modern, compact, and lightweight design, these controllers save space and your strength. Our straight-forward controls allow you to easily sweep, step, ?ne-tune and modulate either by the press of a button or via the GPIB or RS-232 interface and your PC.

Features:
|
|
Automated Wavelength Scans
|
|
Easily perform wavelength scans over part of or the entire tuning range of the laser. Just set the start and stop wavelengths and scanning speed and press the scan button.
|
|
High-Speed Current Modulation
|
|
Modulate the laser amplitude with a 3-dB bandwidth of 1 MHz through the controller’s current-modulation input.
|
|
Easy Wavelength Modulation
|
|
Convenient wavelength modulation for spectroscopy or stabilization experiments is provided by a PZT actuator on the tuning element. Driving the PZT through the input on the back panel of the controller allows you to directly modulate the laser wavelength with a 3-dB bandwidth of 2 kHz.

Complete Computer Control and LabVIEW™ Programs
|
|
Anything you can adjust from the front panel can be controlled through RS-232 or GPIB (IEEE-488) interfaces. In remote mode, you still have access to the frequency-modulation input, allowing you to dither the frequency as you perform automated wavelength scans.
|
|
Detector Input
|
|
The general-purpose detector input on the back panel allows you to implement digital control algorithms and is particularly useful for stable-power wavelength scans, background correction in applied spectroscopy experiments, and wavelength stabilization.
