Single-frequency, injection-seeded Q-switched operation of resonantly pumped Er:YAG ceramic laser at 1645 nm

Single-frequency, injection-seeded Q-switched operation of resonantly pumped Er:YAG ceramic laser at 1645 nm

A single-frequency Q-switched Er:YAG polycrystalline ceramic laser is reported for the first time. The ‘Ramp–Hold–Fire’ injection-seeding technique was employed to obtain single-frequency pulses, with an Er:YAG NPRO as a seed laser. Single-frequency laser operation was obtained with pulse energy of...

Zusammenfassung:A single-frequency Q-switched Er:YAG polycrystalline ceramic laser is reported for the first time. The ‘Ramp–Hold–Fire’ injection-seeding technique was employed to obtain single-frequency pulses, with an Er:YAG NPRO as a seed laser. Single-frequency laser operation was obtained with pulse energy of 4.7 mJ, pulse width of 250 ns and pulse repetition rate of 200 Hz.
