1511894 Magneto-optical playback heads SIEMENS AG 6 June 1975 [23 July 1974] 24354/75 Heading G5R [Also in Division H1] A reading head for data stored on a movable magnetic tape 8, Fig. 1, comprises the integral combination of a magneto-optical flux detector 1 and a laser 2, the optical output 9, 10 of the laser being modulated by the detector. The laser is formed by epitaxial growth of an Nd-YAG layer on a transparent sapphire substrate 3, and has corrugated surfaces adjacent its output emitting ends which function as a resonator by providing distributed feedback. The magneto-optical flux detector comprises a YIG layer epitaxially grown on the laser layer. Since the detector layer 1, the laser layer 2 and the substrate 3 have progressively smaller refractive indices n 1 , n 2 , n 3 , laser emission is confined to layers 1 and 2 and the detector layer is effectively located within the resonator. The detector layer can therefore modulate the output modes and modes distribution of the laser output in accordance with the magnetic tape data, the changes in laser emission being in the form of divergency, direction or intentisty distribution, or power. The laser layer is pumped by light 5 directed through the substrate, the light source consisting of either a single lamp or an array of luminescent diodes, Fig. 2 (not shown). Optionally the space between the magnetic tape 8 and the detector layer 2 may be filled with a grown or vacuum-deposited magnetic layer having a refractive index less than n 1 . Pararallel end face resonator mirrors may alternatively be used.

SCALABLE AND STABLE, CW PHOTOLYTIC ATOMIC IODINE LASER

The present invention is a scalable and stable, cw photolyti-cally excited atomic iodine laser (10) operating at 1.315 microns. An initial power level of 55 watts/liter was obtained via the cw photolysis of an alkyl-iodide gas (20) like C3F7I. The greatly en-hanced laser performance was achieved using a microwave (16) excited, electrodeless Hg plasma lamp (18) excited with a d.c., low ripple (1%) cw microwave radiation. Both high flow, air cooling and above ambient temperature (50 - 150 °C) liquid, dimethyl polysiloxane cooling of these high pressure Hg lamps (atmospheres) provided long lifetime operation with the latter promoting stable laser operation. Transverse flow for the remo-val of the quenching by-product I2 is incorporated into the laser (10). To insure good laser amplitude stability, both the high power magnetrons (operated at 1.5 KW but capable of 3 KW performance) and the lamp (18) (normally Hg) are liquid cooled, respectively by H2O and dimethyl polysiloxane. The use of the high ultraviolet transmissve properties of the dime-thyl polysiloxane lamp coolant removed the requirement for large flow air cooling (150 cfm) of the lamps (18); thereby, allowing good amplitude stability. Elimination of air coolant en-abled use of a slow N2 purge; thereby preventing the formation of ozone, 03, a strong absorber of the UV radiation exciting this cw photolytic atomic iodine laser (10). The scalable, prolonged and stable operation of this cw photolytic iodine laser system (10) is possible via use of closed cycle, condensative/evaporative fuel system coupled to a high flow (10 meters/sec), internal blower for heavy gases (20) like the alkyl iodide C3F7I. Over an excitation length of 25 cm, an average small signal gain coefficient of 2 %/cm is produced by exciting the transvesely flowing C3F7I from one side. High powers are achievable by exciting the gas (20) from both sides, increasing the ultraviolet lamp radiation with higher microwave power and/or more efficient UV ...

SLAB LASER AND AMPLIFIER AND METHOD OF USE

A slab laser and its method of use for high power applications including the manufacture of semiconductors and deposition of diamond and/or diamond-like-carbon layers, among other materials. A lamp driven slab design with a face-to-face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface is utilized. A side-to-side amplifier configuration permitting very high average and peak powers having scalability is also disclosed. Cavity filters adjacent to pump lamps convert the normally unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser, thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power.

Solar powered iodine laser

A stabilized satellite device located outside of the earth's atmosphere collects solar energy, converting it by photochemical or other laser interactions into a beam of infrared energy directed toward a power utilization station, such as at the earth's surface, the wave length of the infrared energy lying within a non-attenuating pass-band in the earth's atmosphere. Sections of the laser are cooled by a directive radiator system aligned toward outer space.
