Abstract

Characteristics of a flashlamp pumped Ti:sapphire laser seeded by an external cavity laser diode (ECLD) is reported. The ECLD consists of a commercially available laser diode, a diffraction grating and a tuning mirror. The laser diode does not have an anti-reflection coating. The tuning mirror is used to feed the first order diffraction beam back to the laser diode. The ECLD has the property of mode-hopping suppression that is useful for the laser radar applications. The linewidth (FWHM) of the ECLD is about 0.3 pm with an output power of 6 mW and the wavelength tuning range is 11 nm from 769 nm to 780 nm. Injection into the cavity of the Ti:sapphire laser is made through a polarizing prism located between a Ti:sapphire rod and a pockels cell. The linewidth (FWHM) of the flashlamp pumped Ti:sapphire laser injection seeded by the ECLD was about 0.55 pm consequently. This laser system is applied to observe the potassium layer in the mesopause region.
