A simple spice model for traveling wave semiconductor laser amplifier

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 7 2007
Abhirup Das Barman
Abstract An equivalent lumped element electric circuit model for traveling wave semiconductor laser amplifier has been developed using the rate equation for carriers. SPICE simulation of the circuits gives results in close agreement with the experimental data and values from sophisticated analyses. The modulation bandwidth and transient response were examined by including parasitic elements in the intrinsic model. © 2007 Wiley Periodicals, Inc.

When a laser pulse propagates through a pair of diffraction gratings, its carrier-envelope phase depends strongly on the separation of gratings. This effect has been used to stabilize the carrier-envelope phase in chirped pulse laser amplifiers. (Picture: E. Moon et al., pp. 160,177, in this issue) [source]

Ba(Mg,Zr,Ta)O3:Nd3+ fine-grained ceramics: a novel laser-gain material with disordered structure for high-power laser systems

LASER PHYSICS LETTERS, Issue 4 2009
A.A. Kaminskii
Abstract Nd3+ -ion doped Ba(Mg,Zr,Ta)O3 ceramics is introduced as a new gain crystalline materials for lasers and laser amplifiers. By pumping laser-diode radiation at 300 K its CW stimulated emission at 1.0754 ,m wavelength was recorded. Some optical, spectroscopic and mechanical properties were measured as well.
