摘要： A system for tuning one or more second radiant sources relative to a first radiant source may include a coupler configured to combine output signals from the first radiant source and a second radiant source to generate a heterodyne signal containing a frequency difference between the output signals from the first radiant source and the second radiant source. A photodetector may be configured to convert the heterodyne signal into an electrical signal containing the frequency difference. A spectrum analyzer may be configured to measure the frequency difference in the electrical signal and generate a precise difference value. A controller may be configured to adjust a wavelength of the second radiant source relative to that of the first radiant source based on the precise difference value. Laser spectroscopy may be performed by passing the output signals from the first radiant source and the second radiant source through a sample volume and detecting reflected or emitted radiation.

摘要： To drive a single-mode laser device using a differential-pair output stage, collector terminals of transistors forming the differential-pair must be maintained at a predetermined potential. Since the potential dropped across the laser device is only about 1V, a Schottky diode connected between a cathode of the laser device and a second supply rail raises the cathode about 0.5V above the voltage of the second supply rail.

摘要： An optically pumped semiconductor laser device having a substrate (12) having a first main area (14) and a second main area (16), a pump laser (30) and a vertically emitting laser (40) optically pumped by the pump laser (30) being arranged on the first main area (14). The first main area (14) of the substrate (12) is patterned and has first regions (20) situated at a higher level and also second regions (18) situated at a lower level. The pump laser (30) is arranged on a region (20) situated at a higher level of the substrate (12), and the vertically emitting laser (40) is arranged above intermediate layers (50, 30null) on a region (18) situated at a lower level of the substrate (12). The height difference (null) between the first (20) and second (18) regions of the substrate (12) and the layer thickness of the intermediate layers (50, 30null) is chosen in such a way that the pump laser (30) and the vertically emitting laser (40) are situated at the same level. A substrate which is patterned in this way enables semiconductor layers of the pump laser and of the vertically emitting laser to be applied together in a single epitaxy step.

摘要： After forming domain inverted layers 3 in an LiTaO3 substrate 1, an optical waveguide is formed. By performing low-temperature annealing for the optical wavelength conversion element thus formed, a stable proton exchange layer 8 is formed, where an increase in refractive index generated during high-temperature annealing is lowered, thereby providing a stable optical wavelength conversion element. Thus, the phase-matched wavelength becomes constant, and variation in harmonic wave output is eliminated. Consequently, with respect to an optical wavelength conversion element utilizing a non-linear optical effect, a highly reliable element is provided.

摘要： A laser diode array assembly includes a laser diode array and a memory device integrally packaged with the array. The memory device includes operational information concerning the array. The memory device is accessible by a host external operating system which determines the manner in which the array is to be powered based on the operational information. The memory device may have the capability to be written to such that tie external operating system can record in the memory device significant events such as extreme operational conditions, operational faults, and the on-time or shot-count of the array. The assembly may include sensors to which the operating system is coupled. The assembly may further include a processing means to monitor the sensors and provide real-time updates to the external operating system such that laser diode array is continuously powered in an optimal manner.
