Ti: Sapphire Continuous Wave Laser


Ti: Sapphire continuous wave laser system with wide tuning range and narrow line width.

  • Wide wavelength tuning range of 700-1000 nm (with a set of optics)
  • 1.8 W at 800 nm average power output
  • Integrated laser pump option (2W to 10W)
  • Standard option for a narrower generation linewidth (<2 GHz)
  • PC connection for automatic wavelength optimization
  • Optional integrated fiber coupling
  • Integrated spectrometer and power meter (optional)
Continuous-wave Ti:Sapphire laser features broad wavelength tuning range and finds itself as a useful tool for many fields of fundamental research, especially different spectroscopy application. The wavelength tuning is carried out by a birefringent Lyot filter and can be either manually controlled or motorized via a step motor with USB connection to a PC. Two etalons can be optionally placed into the resonator in order to narrow the linewidth of the generated radiation down to 2 GHz.

The CW Ti:Sapphire laser needs to be pumped by a CW DPSS or Ar-Ion pump laser  at 532 nm. Our company offers the oscillators without the pump laser, as well as a version with integrated pump lasers with pump power varying from 2 W to 10 W.

Optional fiber-coupled modification is available. The radiation is steered into a fiber with 4 um core diameter. The optical scheme allows easy switching between the free-space and the fiber outputs via a flip mount.
