Broadband tunable excimer laser studies
The principal purpose of this work was studies of the broadband tunable excimer laser namely XeF(C ..-->.. A). Wideband tunability of this excimer laser was first demonstrated with a simple compact dispersive stable cavity in a transverse e-beam pumped geometry. More recently, a series of experiments was performed to control the XeF(C ..-->.. A) by dye laser injection. In any low-gain, short-pulse laser systems, rapid build-up of the optical field within the resonator is critical to good laser performance and extraction efficiency. Simultaneous injection of a seed signal into the cavity with laser-pumping excitation can create a much faster increase in the intensity of the optical field. This rapid build-up of the optical field will aid the competition against radiative emission from the high-gain XeF(B ..-->.. X) transition and non-radiative quenching of the XeF excimers by halogen donors and other constituents of the laser gas mixture. In order to gain a better understanding of the injection control process in XeF(C ..-->.. A) laser, a semi-empirical model using a pulsed regenerative amplifier approach was established with good accuracy. A set of coupled rate equations are used for this purpose. Some key factors in cavity and pumping source design are addressed.
