Y Nishijima, K Shinohara
A Pb(1-x)Sn(x)Te single-mode laser with a buried heterostructure has been developed by use of a two-step liquid-phase epitaxial growth. The active-layer size was calculated for fundamental transverse-mode operation. Tin diffusion was simulated in the active layer during the second growth step, and the results were used to select the optimum growth temperature. Analysis of the crystal-growth mechanism in the buried-heterostructure formation enabled us to develop a new growth method. The laser we developed showed single-mode operation with a wavelength of 8 ┬Ám and a power of 1...

The injection effect of weak Stokes seed radiation is demonstrated in a para-H(2) Raman laser. Injected radiation from a PbSnTe diode laser as low as several microwatts resulted in an enhancement of 4 orders of magnitude in the output Stokes energy and a reduction in the pumping threshold energy of 22%. Characteristics of the injection are investigated as functions of the pumping energy, the Stokes seed frequency, and the polarization.

An optically pumped amplifier of high-pressure NH(3) has been successfully applied to wide-range amplification of a PbSnTe tunable-diode laser. A continuously broadened gain width of more than 20 GHz was achieved with a NH(3)-He mixture.

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
