✦ Synopsis

Gain-switched Nd:YAG microchip lasers have produced 1 MHz repetition rate, single-frequency pulses with a pulse width of 32 ns. This is, to our knowledge, the highest repetition rate obtained in a single-frequency gain-switched solid state laser. The laser peak power and pulse width are mainly determined by the peak power of the pumping pulse and independent of the pulse repetition rate. Single-frequency operation is realized by temperature-tuning of the laser wavelength to the peak of the gain profile. Gain-switching at high repetition rates significantly improves the optical efficiency of the device.
