| Abstract: | The design consideration of high power diode laser at
wavelength of 980 nm as pump source for erbium doped glass eye safe laser at
wavelength 1.54  m
is presented here. The design of high power laser requires precise control of
waveguide dimensions, material and doping profile of layers. The maximum
optical power is proportional to transverse optical spot size. The transverse
optical spot size and threshold current density have been calculated with
transverse waveguide thickness. The effect of current spreading on threshold
current density is calculated. The geo-scientific application of eye safe laser
is also presented. |
