Sample on piezo stage
Moves a mounted sample through static, lateral, depth or raster scans, and can record writing in resin.

A sample stage translates the specimen relative to the illumination and collection optics. Lateral motion samples different positions across a specimen; axial motion changes its position along the optical axis. A physical stage has finite travel, response time, and positioning accuracy.
In OpticalSetup
The stage combines a mounting aperture with the sample's optical modes, including the χ⁽²⁾ channel that gives each beam's second harmonic and the sum frequency of a pair, and the two-beam signals — sum frequency, CARS and stimulated Raman — that only appear while both pulses reach the specimen together. Select a static position, long-axis scan, beam-axis depth scan, or synchronized raster, then set the travel and frequency. At 90° rotation, a horizontal beam crosses the sample and a long-axis scan moves it vertically on the canvas.
Scanning moves the specimen, not the arms, so it does not change the arrival difference between two beams: that is set by their optical paths, and a delay line or a matched arm is what fixes it.
The example moves an illuminated sample laterally. For a writing demonstration, choose photocurable resin, enable voxel preview, and use a pulsed source. Marks record traced pulse arrivals in the moving sample.
The workbench shows a two-dimensional projection. Resin marks are a visual arrival history, not a prediction of dose, polymerization threshold, cure kinetics, voxel size, or three-dimensional fabrication. Piezo hysteresis and mechanical settling are not simulated.
