Diode-pumped passively mode-locked Nd:CTGG disordered crystal laser

A diode-pumped passively mode-locked Nd: CTGG disordered crystal laser has been experimentally demonstrated for the first time to our knowledge. Mode locked with a semiconductor saturable absorber mirror, the laser generated 5.2 ps pulses at a repetition rate of 88 MHz. After intracavity dispersion compensation, the mode-locked pulses were shortened to 4.3 ps. Multiple emission wavelengths of the Nd:CTGG laser could be synchronously mode locked under dispersion compensation.
