Patent Number Title Of Patent Date Issued
8248700 Systems and methods for coherent beam combining of laser arrays August 21, 2012
Systems and methods for coherent beam combining are provided. In some aspects, a system may comprise a first array of laser emitters configured to emit a first array of output beams along a first optical path. The system may also comprise a first array of collimating lenses configured
7483146 Systems configured to provide illumination of a specimen or to inspect a specimen January 27, 2009
Systems configured to provide illumination of a specimen or to inspect a specimen are provided. One system includes a light source configured to generate pulses of light at a repetition rate. The system also includes optical elements arranged in a first interferometer configuration f
6526071 Tunable laser transmitter with internal wavelength grid generators February 25, 2003
The present invention provides a continuously tunable external cavity laser (ECL) with a compact form factor and precise tuning to a selected center wavelength of a selected wavelength grid. The ECL may thus be utilized in telecom applications to generate the center wavelengths for any c
6282215 Continuously-tunable external cavity laser August 28, 2001
The present invention provides a continuously-tunable external cavity laser (ECL) with a compact form factor and precise tuning. A novel interference filter which may be used to tune the ECL provides an absence of mode-hopping and reduced feedback from both spurious interference and
6108355 Continuously-tunable external cavity laser August 22, 2000
The present invention provides an external cavity laser that has wide-range continuous tuning and is compatible with a compact, robust, inexpensive form factor. In an embodiment of the invention a tunable external cavity laser is disclosed. The laser includes a laser amplifier, a ret
6014216 Architecture for air-turbulence-compensated dual-wavelength heterodyne interferometer January 11, 2000
An apparatus for measuring the change in position of a stage mirror with reference to a reference mirror when the stage mirror moves between first and second positions. The apparatus includes a light source for generating first and second coincident light beams, the first light beam havi
5732095 Dual harmonic-wavelength split-frequency laser March 24, 1998
The ideal source for air-turbulence-corrected distance-measuring interferometry is a single laser that generate overlapping beams at two widely separated wavelengths .lambda..sub.1 and .lambda..sub.2. At least one of the wavelengths, as well as the wavelength ratio, must be known to
5325378 Misalignment-tolerant, grating-tuned external-cavity laser with enhanced longitudinal mode selec June 28, 1994
A grating tuned external cavity laser having improved mode selectivity and stability. A cylindrical lens is positioned between a laser amplifier and a prism pair beam expander to focus the laser beam to form a linear spot on a grating. The location of the cylindrical lens between the las
5263037 Optical oscillator sweeper November 16, 1993
An electrically tunable optical oscillator. An acoustooptically tunable filter is located in a feedback path of an optical oscillator. The filter non-collinearly diffracts the light signal to selectively tune the oscillator. In one embodiment the light signal passes twice through a s
5177750 Misalignment-tolerant, grating-tuned external-cavity laser with enhanced longitudinal mode selec January 5, 1993
A grating tuned external cavity laser having improved mode selectivity and stability. A cylindrical lens is positioned between a laser amplifier and a prism pair beam expander to focus the laser beam to form a linear spot on a grating. The location of the cylindrical lens between the las
5161165 Multimode stabilized external cavity laser November 3, 1992
An etalon stabilized external cavity laser. The present invention is embodied in an external cavity laser and utilizes a servo circuit to adjust the angle of an intra-cavity etalon to suppress multimode operation of the laser. The servo circuit employs a diode detector to detect a beat
5140599 Optical oscillator sweeper August 18, 1992
An external cavity laser is formed by feeding back light from a laser through two or more acoustooptic tuneable filters back to the laser. The Doppler shifts introduced by the filters do not entirely cancel. The net Doppler shift caused by the filters is continuously tuned to cause the
4942583 Misalignment-tolerant, grating-tuned external-cavity laser July 17, 1990
A grating tuned laser system having an anamorphic optical section (72) that produces a line image on the grating (73). This system is insensitive to tilt of the grating (73) about an axis (T) perpendicular to the rulings (74) of the grating (73). An embodiment that utilizes a degenerate
