Abstract

The mode-locked Nd:glass laser is a well-known source of short pulses due to its large fluorescence Iinewidth (5.3 THz). Traditionally, this laser has been pumped using flashlamp excitation or end pumping using an argon ion laser operating at 514 nml. More recently, the development of diode laser technology has lead to the use of diode lasers as pump sources for actively modelocked neodymium-doped solid state lasers, including the Nd:glass laser. The Nd:glass laser is particularly suitable for pumping with laser diodes due to its wide absorption linewidth in the region of 800 nm. We have investigated both acousto-optic amplitude modulation (AM) mode-locking and electro-optic frequency modulation (FM) mode-locking of the laser-diode-pumped Nd:glass laser.
