Synchronously pumped picosecond all-fibre Raman laser based on phosphorus-doped silica fibre.
Reported for the first time is picosecond-range pulse generation in an all-fibre Raman laser based on P₂O₅-doped silica fibre. Employment of phosphor-silicate fibre made possible single-cascade spectral transformation of pumping pulses at 1084 nm into 270-ps long Raman laser pulses at 1270 nm. The highest observed fraction of the Stokes component radiation at 1270 nm in the total output of the ...
متن کاملNdYAG laser photocoagulation in the dog stomach.
Considerable discussion still centres around the relative merits of the Argon and Neodymium Yttrium Aluminum Garnet (NdYAG) lasers for the endoscopic treatment of gastrointestinal haemorrhage, although both are undoubtedly effect. We have carried out experiments to elucidate which factors determine the safety and efficacy of NdYAG laser photocoagulation. Histological studies on normal gastric m...

682 infrared range of the electromagnetic spectrum. Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a ...
متن کاملLaser-diode-pumped Nd:YAG active-mirror laser.
We describe a simple design, laser-diode-pumped cw Nd:YAG active-mirror laser and present a thermal analysis of the crystal. A cw output power of 2.4 W and an M(2) beam quality value of less than 1.9 at an incident pumping power of 8.9 W were obtained. From the thermal analysis we predict that the output power can be increased by increasing the pump beam diameter and the pump power at a constan...
متن کاملA pumped atom laser
The invention of the optical laser, a bright, pumped source of coherent photons, has revolutionized optics and precision measurement, led to global high bandwidth communication and enabled non-linear optics, quantum optics, and experimental investigations of quantum information, quantum computing and quantum cryptography. The atom laser, a bright, coherent matter wave, holds similar promise for...
