We report the measurement of the effective upper laser level lifetime from an end-pumped Q-switched Tm,Ho:YLF laser. When the pump power is 1.58 W, the effective upper laser level lifetime is only 2.5 ms, which is less than the fluorescence lifetime (∼16 ms) of the upper laser level. The dependences of the effective upper laser level lifetime on the pump power and the temperature of laser crystal...
A comparative study of the nonlinear optical properties and ultrafast dynamics of three oligomers were carried out using femtosecond laser spectroscopic techniques. All oligomers showed intense fluorescence emission induced by a two-photon absorption process. Relaxation features with parallel and perpendicular polarization configurations were investigated in a one-color pump–probe experiment at 400 nm...
