Equipment

The experimental setup of a laser measurement typically comprises three components: The laser light source, the test device and the detection system.

Laser systems

• Pulsed, some in single-mode operation, with frequency conversion and in combination with dye lasers or optical parametric oscillator
• Flashlamp-pumped dye laser delivering 2 J/pulse at 10 Hz repetition rate, pulse duration 2 µs
• Tunable excimer laser in the UV range
• 6-pulse Nd:YAG laser system for laser Raman scattering
• Dual head Nd:YAG laser for particle image velocimetry
• Diode-pumped solid state lasers with repetition rates >1 kHz

Combustion tes rigs

• Standard burners for turbulent jet diffusion flames and swirl flames
• Burner for confined premixed jet flames
• Test rig for ignition experiments in spray flames
• Various calibration flames with well-defined temperature, species concentrations and soot distributions
• High pressure test rig for the study of fuel injection systems
• High pressure burner for laminar and turbulent flames up to 20 bar
• High pressure test rig for small gas turbine relevant combustors

Detectors

• 

  Mobile laser container for temperature measurements by CARS
  CCD cameras and diode arrays with image intensifiers
• Double exposure CCD camera with image intensifier
• Highspeed CMOS cameras image intensifiers
• Different photomultiplier tubes and diodes
