September 1, 2007 Mesa Photonics releases a new ultrafast laser pulse measurement system based on frequency resolved optical gating: FROG Scan
Our optical delay line blows away stepper motor stages
High Speed, 1 ms response time
150 nm precision (525 nm for 3.5 cm stage)
200 nm short term repeatability
50 ppm long term repeatability
1 cm range, 3.5 cm available
Interface with LabView and other programs.
No backlash
No deadband
Bolts directly to optical table
Optics included
USB control
up to 30 mm beam spacing (15 mm nominal)
15 mm aperture (for the 1 cm delay)
Our optical delay stage uses a high performance advanced voice coil-based positioning technology to provide positioning accuracy to 1 fs delay (assuming double pass) -- it can be positioned to anywhere in its one centimeter range to a precision of 150 nm. No backlash, no hysteresis, and no drive trains to wear out as with stepper motors. It’s fast -- response times as fast as 1 ms. Control from LabView over a simple USB connection. Complete with controller, power supply, stage, LabView interface and retroreflector as shown.
Because of the LabView VIs, the stage can be integrated easily in to your experiment Also, the high speed allows you to take advantage of averaging and removal of low frequency 1/f noise in your data collection.
Shown on the right is the 3.5 cm version of our new, easy to use ”no align” design. Just place stage directly in a beam to get the optical delay. The original beam is minimally deviated.
