Diode pumped erbium laser. Both lasers are constructed in the bounce geometry with quasi continuous wave qcw diode pumping. 17 w of output power and 173 slope efficiency with respect to the launched pump power at a wavelength of 271 um are demonstrated from a double clad erbium doped zblan fiber diode pumped at 790 nm. Intracavity pumping of yberphosph ate glass with a diode pumped ndy ag laser allows efficient tunable operation of the th ree level er laser in the 1530 1610 nm range.

Thanks to the coincidence of the wavelength 975 nm of commercially available high power laser diode ld and the absorption band of the erbium ion the output power of ld pumped continuous wave. A maximum measured output power of 54w and a slope efficiency of 21 were obtained by both end pumping. T1 scaling up laser diode pumped mid infrared fiber laser to 10 watt level.

A diode pumped actively q switched 28 mm fiber laser oscillator with an average output power of more than 12 w has been realized through the use of a 35 mm core erbium doped zblan fiber and an. In eryag pulse energies of up to 31mj slope efficiency of 126 and a red shift in laser wavelength are observed with a final and dominant wavelength of 2936mm. Energy transfer from the er3 lower laser level to a pr3 codopant decreases ground state bleaching and excited.

Au zhu xiushan. The 980 nm products that are used in erbium doped fiber amplifiers offer operating power levels from 100 mw to 1000 mw. N2 10 watt level diode pumped erbium doped zblan fiber lasers at 27mm under different ways of pumping are studied and analyzed through numerical simulations.

Diode pumped erbium cascade fiber lasers abstract. Au jain r. Diode pumped solid state lasers tend to be much more efficient and have become much more common as the cost of high power semiconductor lasers has decreased.

The s26 s27 s28 and s29 series are semicooled at 450c for diode laser operation which provides for a significant reduction in tec and overall power consumption. A multi longitudinal mode 1535 nm output of more than 80 mw typically results with a 1 w 808 nm pum p diode. Laser pumping solid state lasing media are typically optically pumped using either a flashlamp or arc lamp or by laser diodes.

Cascading the 4 i 112 4 i 132 transition at 28 mm and 4 i 132 4 i 152 transition at 16 mm offers a solution to the thermal management of high power er 3 doped fluoride fiber lasers.
