Development of continuous wave and mode locked titanium sapphire laser
A Ti:sapphire laser was developed based on self mode-locking technique using a 'Z' folded cavity. Diode pumped solid state laser Verdi 5 was used as a pumping source with fundamental wavelength of 532 nm (suitable for the absorption band in Ti:sapphire crystal). Laser cavity was aligned by...

Diode pumped solid state laser Verdi 5 was used as a pumping source with fundamental wavelength of 532 nm (suitable for the absorption band in Ti:sapphire crystal). Laser cavity was aligned by a set of mirrors with a high reflectivity of 99.8% to reflect the beam within the range of 720 nm to 820 nm, and an output coupler with a 5% transmission. A pair of prism was employed to control the dispersion for producing femtosecond pulse. The pulse was initiated via an external perturbation. The stability of the laser was sustained by providing a water cooling system. The laser operated in two modes which are continuous wave mode (CW) and pulse mode with mode-locked (ML) mechanism. The maximum output power of the CW Ti:sapphire laser is 1.12 W corresponding to a pumping power of 5.5 W and the efficiency of 26%.
