ORPHEUS kollinear

Abstimmbares OPA-System ORPHEUS


Orpheus ist ein Optisch-Parametrischer Verstärker (OPA), der mit einem Femtosekunden-Pumplaser (Pharos) gepumpt wird. Vergleichbar mit den weltbekannten Topas-OPA Systemen, erzielt Orpheus exzellente Strahlparameter und Leistungsdaten. Ein großer Tuningbereich, ein kompakter Aufbau und ein computergesteuertes Tuning sind weitere Vorteile des Orpheus.

Tab 1

  • Built on well known TOPAS OPA basis
  • Repetition rate up to 1 MHz
  • High energy conversion into parametric radiation
  • Near bandwidth and diffraction limited output
  • Adaptable to different pump pulse energy, wavelength and pulse duration
  • Full computer control via USB port and dedicated software
  • Fundamental and second harmonic of pump laser available from the same enclosure
  • Compact footprint when combined with Pharos pump laser <0.5 square meter

Parametric amplification is performed with the second harmonic of pump laser. 515 nm pump beam is generated inside of OPA unit with computer controlled angle adjustment. Fresh/residual fundamental and second harmonic radiation (1030 nm and 515 nm respectively) are accessible from dedicated output ports. ORPHEUS provides tunable OPA output (630-2600 nm) with residual second harmonic and fundamental radiation beams at the same time.
Femtosecond pulses, high power tunable output together with flexible multi-kilohertz repetition rate make the tandem of PHAROS and ORPHEUS an invaluable tool for multiphoton microscopy, micro-structuring and spectroscopy applications.
Several ORPHEUS can be pumped by single PHAROS laser providing independent beam wavelength tuning.
