Ti:Sapphire CW Laser

Ti:Sapphire CW Laser


Continuous-wave Ti:Sapphire laser features broad wavelength tuning from 700 to 1000nm. Such lasers sources can be used in many fields of research as different spectroscopy applications and semiconductor research. The wavelength tuning can be either manually controlled or motorized via a step motor with USB connection to a PC. We offer other options like integrated pump laser and fiber-coupled modification.

Continuous-wave Ti:Sapphire laser features broad wavelength tuning range (700-1000 nm), typical tuning curves see data sheet) 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 (see laser layout, data sheet).
