Low noise fiber lasers

All laser outputs always contain some amount of noise due to the influence of quantum noise and several technical fluctuations. Quantum noise is typically associated with spontaneous emissions in the gain medium. Technical fluctuations include temperature fluctuations, laser resonator vibrations, excess noise of the pump source, etc. Different types of lasers may suffer from different...

Picosecond and femtosecond lasers

Ultrafast lasers emit ultrashort pulses with the duration of femtoseconds or picoseconds. These types of lasers and their applications are researched in the field of ultrafast laser physics and ultrafast optics. Ultrafast lasers are highly useful in a number of scientific applications as the duration of the optical pulse approaches the timescale of atomic processes....

Tunable fiber laser applications

Tunable fiber lasers’ main characteristic is the ability of the wavelength to be tuned or adjusted. This process is referred to wavelength tuning. Tuning of the fiber laser may occur over a wide range, which is highly desired for certain applications. Tunable fiber lasers are called wavelength agile if the wavelength tuning may be performed...
