A CW dye laser has been used to study transient optical gain on the B →X electronic transition of iodine monofluoride. By placing the gain generator inside the CW dye laser cavity, gain was readily observed even at levels too small to support lasing in a low loss cavity. Transient phenomena, including V–T energy transfer, were easily observable. An analysis of the intracavity gain detection technique revealed a method for estimating optical gain. The technique should be readily applicable to other systems.

Abstract Efficient spectral narrowing and accurately reproducible tuning of a dye laser has been achieved by the combination of a low-loss narrow-band interference filter and a solid-quartz-plate-Fabry-Perot-etalon. Bandwidths as small as 5-10-3 Å were obtained by this simple system increasing the spectral density by a factor of at least 2 · 103.

Performance Capability

High-voltage converter employing IGCT switches (VDC=2800 V) for traction application is presented. Such a power traction drive operates with an unstable input voltage over 2000⋯4000 V DC and with an output power up to 1200 kW. The original power circuit of the high-voltage converter is demonstrated. Development of the attractive approach to designing the low-loss snubber circuits of the high-frequency IGCT switches is proposed. It is established on the complex multilevel analysis of the transient phenomena and power losses. The essential characteristics of the critical parameters under transient modes and the relation between the snubber circuit parameters and the losses are discussed. Experimental results for the prototype demonstrate the properties of new power circuit. The test results confirm the proposed high-voltage converter performance capability as well as verifying the suitability of the conception for its use in the Russian suburban train power system and other high-voltage applications.
