A wide variety of applications require high peak laser intensity in conjunction with a narrow spectral linewidth. Typically, injection-locked amplifiers have been employed for this purpose, where a continuous wave oscillator is amplified in a secondary external resonant amplifier cavity using a pulsed pump laser. In contrast, here we demonstrate a setup that combines a CW Ti:sapphire oscillator and pulsed amplifier in a single optical cavity, resulting in a compact system. Dichroic beam combination of blue wavelength semiconductor diodes and the green wavelength of a Nd:YAG laser allowed the simultaneous excitation of the Ti:sapphire crystal by both continuous wave and pulsed pump sources. A linewidth of <2MHz is achieved in continuous wave operation, while the linewidth increases to about 10MHz in the combined CW + pulsed mode with a pulse duration of 73ns. A peak pulse intensity of 0.2kW is achieved, which should enable efficient single-pass second harmonic generation in a nonlinear crystal.

“…Much of the recent research focus has been on the development of diode-pumped mode-locked oscillators [35][36][37] [38], with a recent review [39] summarizing many of the developments. Though some work has been done in characterizing CW operation [40][41] [42], we are only aware of our groups own system featuring single-frequency CW operation [43][44] of a diode-pumped Ti:sapphire laser. The beam quality of high power visible diode lasers in the blue-green wavelength region is fairly poor.…”
