We report a tunable, narrow linewidth and high beam quality continuous-wave (CW) yellow laser system at 589 nm. The system is an all solid-state design employing single-pass sum-frequency generation in a KTP crystal by mixing the 1064 nm with 1319 nm lines of two side-pumped Nd:YAG enforcing unidire
## Abstract A delayโtime tunable, actively modeโlocked erbiumโdoped fiber ring laser is demonstrated by using a voltageโcontrolled phaseโlocked phase shifter as an inherent timing module. By changing the voltage from โ3.35 to 3.6 V, the maximum tuning range of the phase and the delay time of the op
