Generation of mode-locked pulse in non self-starting Ti:sapphire laser

Generation of mode locked pulse from non-self starting Titanium Sapphire laser is reported. Initially the output power of the Ti:sapphire laser was detected at various cavity lengths. The result shown that the stability region was found in the range between 104 to 106 mm. However the mode locked signal was only realized within 100 micron a distance apart at the near boundary of the stability region. The distribution of the mode lock pulsed in the stable zone is operating in a normal Gaussian profile
