Local High-Intensity Cryogenic Cooling

1966
The applications of cryogens are many and varied» A recent application utilized a cryogenic system to remove heat from a space simulator solar radiation source. The source, a 5-kW compact xenon arc lamp, was housed in a small leak-tight enclosure and operated within the simulator chamber on a movable on-axis system. The heat generated by the source had

High power cryogenically cooled Ho:YAG laser

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
High energy sources operating around 2 μm are of interest in applications such as LIDAR and material processing and have also been used effectively as pump sources for high-energy mid-lR non-linear conversion, an established approach for generating mid-IR lasers. Commonly used bulk laser materials are Ho:YLF and Ho:YAG. However, at room temperature the

Cryogenically Cooled Infrared Interferometric Spectrometers

1981
Abstract : Very sensitive Fourier transform spectrometers (FTS's) have been developed for infrared measurements utilizing advanced technology to achieve stable operation at very low temperatures. All of the structural, optical, and detector components used to construct these spectrometers are cryogenically cooled to improve the sensitivity of their ...

Survey of Cryogenic Cooling Techniques

1972
Abstract : A survey was made to determine the state of the art of various methods of cooling to cryogenic temperatures for potential adaptation to spaceborne systems. The study included evaluation of mechanical closed-cycle refrigerators, open-cycle expendable systems, passive radiation concepts which utilize the low temperature of the deep space ...

Spot-Cooling with a Cryogenic Pump

1964
Many cryogenic designs have recently been proposed to provide cooling down to 150°K. The conventional methods listed below have many faults when used for “spot-cooling”: 1. Dip-type cooling: This is the simplest method of cooling, which involves submerging the object to be cooled in a bath of coolant.

Cryogenically cooled CO–He TEA laser

Applied Physics Letters, 1973
The performance of a transversely excited atmospheric-pressure TEA CO laser under cryogenic conditions is discussed. With the addition of large amounts of helium as a buffer gas, an output energy of 35 mJ was attained. This energy output represents a considerable increase over that previously reported for a similar system.
