Solid-state laser light sheet

svetelny-nuz-perex.jpg The laser light sheet is designed for visualisation and measurement of fluid flow. It is a unique, custom-made, compact, portable system of long-time operation. It employs a high power Nd:YAG laser of adjustable power as a light source and generates a beam which is treated to result in a wedge-like light sheet. The light source allows the geometry of the light sheet as well as the beam convergence to be set up.


  • Nd:YAG laser, max. power output 3 W, wave length 532 nm, continuous power output adjustment
  • beam divergence less than 1.0 mrad, stability of light power output less than ±1 % peak to peak
  • light sheet geometry:
    • continuous adjustment of sheet width from 1 to 40 mm
    • light sheet area can be adjusted in several discrete steps
  • frequency controlled beam modulation
    • with external TTL signal
    • with internal source of adjustable frequency between 1 and 1000 Hz
  • robust tripod – positioning and tilting with respect to longitudinal and lateral light sheet axes
  • π Shaper homogenised beam profile
  • standard TTL signal output for synchronisation with recording device (camera)


Typical applications

  • visualization and measurement of fluid flow
  • suitable for research into fast processes that exhibit 3D flow character
  • jet visualization by introducing particles, smoke or He-filled bubbles (available devices: Safex smoke/fog generator, Sage bubble generator, TSI 3433 powder dispenser)
  • image recording: Olympus i-Speed 2 high speed camera or digital SLR camera
  • suitable for application with fluorescent particles such as Rhodamine B marked particles
