High-Power Laser Thyristors With High Injection Efficiency ($\lambda =890$ –910 nm)

Abstract: This letter shows an experimentally studied approach that increases injection efficiency of high-power laser thyristors emitting in the 890-910 nm spectral band. The developed laser thyristors exhibit 43-W maximum peak output power of laser pulses at 95-nm full width at half maximum duration. At the same time, the maximum amplitude of the current pulse generated in the laser-thyristor circuit reached 90 A.Index Terms-Laser-thyristor, semiconductor laser, thyristor heterostructure.

“…Then, the nonlinear feedback effected by the photogeneration of an electron-hole plasma in the base of the heterophototransistor upon absorption of the emission generated by the laser part [21] must substantially improve the turn-on uniformity in the case of wide (hundreds of micrometers) stripe contacts. In addition, as shown experimentally in [17,22] and theoretically in [21,23], the photoactivation process affects the injection efficiency of the laser-thyristor. A deficiency of the photogenerated electron-hole plasma may give rise to a nonlinear dynamics of the laser pulse being generated and to an increase in the residual voltage across the collector junction [17,24].…”

“…The topicality of the development in this field is due to the prospects for use in a wide variety of practical applications: pumping of nonlinear media for the second harmonic and differential frequency generation [11], fabrication of laser range meters [12,13], and photoactivation of high-voltage switches [14,15]. The results obtained in [16,17] demonstrate that epitaxially integrated laser-thyristor heterostructures can be used to develop high-power compact pulsed emitters. Integration of the functions of a power electric switch with a laser emitter minimizes external parasitic inductive, capacitive, and resistive couplings, which improves the energy efficiency and operation speed, especially in the generation of high-power laser pulses of nanosecond duration and pumping currents with an amplitude of several tens of amperes.…”

“…This results from a collective contribution of the multiple energy states in the InGaAs/GaAs AQW active region [12] . An carrier optical feedback effect has been reported to be exist in the thyristor laser structure, which may improve the optical gain, differential gain, and temperature stability of our AQW thyristor laser [13,14] . The output power versus injection current curve (L-I) of a representative laser is depicted in Fig.…”

“…Однако присутствие ударной ионизации часто трактуется как негативный фактор, который может приводить к разрушению прибора. Тем не менее на сегодняшний день существует множество примеров приборов, в которых управляемая ударная ионизация используется для генерации неравновесных носителей заряда, в основном это структуры транзисторного и тиристорного типа [13][14][15][16].…”
