摘要： A laser apparatus and method is disclosed comprising a first lasant material which is located in an optical cavity and which produces laser radiation of a first wavelength, and a second lasant material which is pumped by radiation from the first lasant material, which absorbs laser radiation at the first wavelength in an amount generally comparable to the Optimum Output Coupling, which functions as the output coupler for the optical cavity and which lases at a second wavelength. The first lasant material and the second lasant material are preferably selected to have minimal losses such that there is a net gain in the cavity.

摘要： A method of initiating a rapid pH change in a solution by irradiating the solution with an intense flux of electromagnetic radiation of a frequency which produces a substantial pK change to a compound in solution. To optimize the resulting pH change, the compound being irradiated in solution should have an excited state lifetime substantially longer than the time required to establish an excited state acid-base equilibrium in the solution. Desired pH changes can be accomplished in nanoseconds or less by means of picosecond pulses of laser radiation.

摘要： Isotopically enriched material can be produced by photopredissociation of gaseous formaldehyde containing mixtures of isotopes of C, H, or O, by laser beams at 32980 cm.sup.-1 or at 32890 cm.sup.-1, or by an argon-ion laser beam at 351.1 nm, or by the tripled frequency of a 1.06 .mu.m neodymium-glass laser beam at approximately 0.35 .mu.m. At wavelengths shorter than 330 nm a paramagnetic gas, especially NO and also O.sub.2 may enhance the enrichment and yield.

摘要： IT HAS BEEN FOUND THAT TYPICAL FACSIMILE SIGNALS DERIVED FROM SCANNING BLACK COPY ON A WHITE BACKGROUND CAN BE PROCESSED IN SUCH A WAY AS TO SUBSTANTIALLY REDUCE THE COMMUNICATION CHANNEL BANDWIDTH REQUIRED TO TRANSMIT A GIVEN AMOUNT OF INFORMATION. IN THE TYPICAL SYSTEM TO BE DESCRIBED THE BANDWIDTH IS REDUCED BY A FACTOR OF TWO TO ONE. PULSES OF MODULATED SUBCARRIER FROM A FACSIMILE SCANNER ARE PROCESSED TO FORM A THREE LEVEL SIGNAL HAVING ONE-HALF THE REPETITION RATE OR FREQUENCY OF THE ORIGINAL SIGNALS AND HENCE ONE-HALF THE FREQUENCY BANDWIDTH. THESE REDUCED BANDWIDTH SIGNALS ARE TRANSMITTED OVER THE COMMUNICATION CHANNEL. AT THE RECEIVING END THE REDUCED BANDWIDTH SIGNALS ARE PROCESSED TO RESTORE THEIR ORIGINAL FORM AND ARE THEN APPLIED TO A FACSIMILE RECORDER. THIS INVENTION PERMITS EITHER TWICE THE INFORMATION TO BE SENT OVER A GIVEN CHANNEL OF RESTRICTED BANDWIDTH OR TO SEND THE SAME AMOUNT OF INFORMATION OVER A CHANNEL HAVING ONE-HALF THE BANDWIDTH.

摘要： An efficient, compact source of coherent radiation in the infrared, visible and ultraviolet portion of the spectrum which is capable of modulation rates over the range from 0 Hz to in excess of 1 GHz. The radiation is produced by optical mixing within the optical cavity of a laser by introducing input radiation into the optical cavity where: (a) the cavity is that of a diode-pumped solid state laser, and/or (b) input radiation is provided by a solid state device selected from the group consisting of laser diodes, laser diode arrays and diode-pumped solid state lasers.

摘要： A method and system for cementing and perforating a wellbore in a single step by coupling a perforating gun with a wiper plug. The method includes injecting cement in a wellbore having casing therein and an annulus between the casing and wellbore. A wiper plug is dropped on the cement having a perforating gun attached to the wiper plug. The plug is forced downward pulling the perforating gun along. The downward motion of the plug in turn pushes the cement out the bottom end of the casing and into the annulus. The cement in the annulus is allowed to set and the perforating gun is activated.
