RESUMO
Simultaneous asynchronous mode locking of two wavelengths in a Nd(3+)-doped fiber laser is reported. The laser operates simultaneously at wavelengths of 1.060 and 1.100 microm where carrier-type passive mode locking is employed for the shorter wavelength and Kerr-type passive mode locking is used for the longer wavelength. The difference between the two repetition rates may be varied over a range from several megahertz to 500 Hz, limited by the onset of pulse interactions at small difference frequencies.
RESUMO
Passive mode locking initiated with a moving mirror is demonstrated in a neodymium fiber laser for what is to our knowledge the first time. Near-bandwidth-limited pulses with a width of 42 fs and energies as high as 1 nJ are generated.
RESUMO
Wavelength tuning and broad-bandwidth operation of a passively mode-locked Nd:fiber laser is demonstrated at 1060 microm. The oscillator pulses are used to seed a bulk regenerative Nd:glass amplifier, and 300-fs transformlimited pulses with an energy of 10 microJ are obtained after 31 round trips at a repetition rate of 500 Hz.
RESUMO
Cross-phase and self-phase modulation are used for self-sustained mode locking of a high-power neodymium glass fiber laser. Stable pulses with a FWHM as short as 70 fs and pulse energies of as much as 1 nJ are generated at a wavelength of 1.064 microm.
