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.
