摘要： A device and method for doubling the frequency of electromagnetic radiation of a given frequency are described. The device comprises a substrate (1) on which is provided a first layer (2) and a second layer (3). One of the first and second layers (2) has a plasma oscillation frequency equal to the given frequency for causing an electric field at twice the given frequency to be produced across the device in response to electromagentic radiation at the given frequency being incident on the device normally of the first and second layers (2and 3). A thus-produced electric field is converted to electromagnetic radiation at twice the given frequency by the said other of the first and second layers (3) which forms a waveguide for electromagnetic radiation at twice the given frequency. A further layer (2') similar to the said one layer (2) may be provided so that the said other layer (3) is sandwiched between the said one and further layers (2 and 2').

摘要： A source of coherent blue light comprises a diode laser for pumping a Nd.sup.3+ doped member of lasant material disposed within an optical resonator for exciting the .sup.4 F.sub.3/2 -.sup.4 I.sub.9/2 laser transition of a wavelength within the range of 0.870 to 0.960 .mu.m. The laser radiation within the optical resonator is doubled by means of a doubler crystal of a non-linear, electro-optic material to produce blue light which is then extracted from the optical resonator as an output beam. A thermo-electric cooler is coupled in heat-exchanging relation with the Nd.sup.3+ doped laser material to improve the efficiency and the doubler crystal is temperature controlled for phase matching to the laser radiation within the range of 0.870 to 0.960 .mu.m. The diode pump laser is preferably either a GaAlAs or GaAs diode laser producing pumping radiation of a wavelength of approximately 0.810 .mu.m. In the case of Nd:YAG end pumped laser material, the laser material is preferably doped to have a high an absorption coefficient as possible and its length is chosen to be within the range of 0.5 to 3 mm. In one embodiment, the lasant material and the non-linear, electro-optic material are disposed in separate optical resonators with the laser resonator optically decoupled from the doubler resonator for inhibiting reflection of optical power back to the laser resonator.

摘要： A fiber-optic communication system for data bursts includes a plurality of nodes, each including a laser diode transmitter. In order to reduce the noise floor of the system, each laser diode receives bias current only when it is transmitting data. Due to the propagation delay between nodes, there is a dead time between data bursts received by each node during which no data signals are received. The bias current of the laser diode is adjusted following each data transmission, so that the light attributable to laser operation during the setting of bias is received during the dead time. The adjustment is accomplished by stepping an up-down counter by one clock pulse following transmission of each data burst.

摘要： A neodymium YAG laser is pumped by a matched laser diode of high efficiency, resulting in a compact, high-efficiency and long-lifetime laser assembly. Output is in the near infrared range, but can be converted to the visible spectrum by an internal frequency doubler. A doubling crystal, which may be a KTP crystal, is placed at an optimum location in the laser cavity. Polarization of the beam may be achieved simply by stressing the YAG rod, prior to frequency doubling.
