A significant enhancement in the mode locking of a KCl:Tl color-center laser has been observed when a length of optical fiber having positive group-velocity dispersion was incorporated within an external control cavity. Pulse durations of ~260 fsec w

Resonant intracavity sum‐frequency mixing of a diode‐pumped Nd:YAG laser and a 100 mW single stripe laser diode, has been used to generate a measured output power of 20 mW of blue laser radiation at 459 nm. This represents a total conversion effi

An efficient, 459-nm, resonantly pumped Nd:YAG sum-frequency upconversion laser is described. The pump beam from a single-frequency 805-nm laser diode was resonantly enhanced inside the laser cavity and summed with the 1064-nm circulating field. A bl

Stable, self-starting operation of a coupled-cavity mode-locked KCl:T1(0)(1) color-center laser has been achieved by incorporating a semiconductor diode optical amplifier into the control cavity. By adjustment of the amplifier drive current, nonlinea

Pulses having durations as short as 60 fsec have been directly generated by a self-mode-locked, dispersion-compensated Ti:sapphire laser. By using an extracavity fiber-prism pulse compressor, pulse durations as short as 45 fsec have been obtained.
