摘要： The present invention provides a laser device wherein one diffraction grating (1) and at least two reflectors (4, 2) are arranged such that two coupled resonators (A, B) are formed for the light path. This laser device is an arrangement forming a first optical resonator (A) comprising a first (4) and a second (2) reflector including in its light path the diffraction by the grating (1). The second reflector (2) is arranged perpendicularly to an order of diffraction of the grating (1). Coupled with the first resonator (A), there is provided a second mirror- reflect ive resonator (B) between a mirror-reflective surface of the grating (1) and the second reflector (2). In the case of the grating (1) having an even number of ports, the second resonator (B) needs completion by a third reflector (3) arranged to reflect light from specular reflection by the grating (1) back to the grating (1). For gratings (1) having an odd number of ports, the second reflector (2) is arranged in parallel to the grating (1). The laser medium (5) is preferably arranged between the first reflector (4) and the grating (1).

摘要： An external cavity laser apparatus and method wherein wavelenght or channel selection (66) is carried independently from adjustment of external cavity optical path length. The apparatus comprises a wavelenght or channel selection tuner (66) and an external cavity tuner, wherein the wavelength tuner is uncoupled from the external cavity tuner. The tuning mechanisms for wavelenght selection (70) and cavity optical path length (68) are configured to operate independently or orthogonally with respect to each other. The wavelength tuner may operate according to a first, channel selection signal, while the external cavity tuner operates according to a second, external cavity adjustment signal. The wavelength tuner and external cavity tuner may operate under the control of the same, or of separate controllers. The channel selection signal may be derived from a look-up table of adjustment parameter data accessed by a controller, and the external cavity adjustment signal may be derived from an error signal from a detector configured to measure external cavity loss.

摘要： The laser light source apparatus comprises a compound cavity (12) and an optical gain medium (4). The compound cavity (12) includes first, second, and third optical reflection members (1, 2, 3) disposed along the optical axis. The first optical reflection member (1) has a light wavelength selectivity. At least one of the first to third optical reflection members (1, 2, 3) can change its own position on an optical axis in relation to the other reflection members. Two of the first to third optical reflection members (1, 2, 3) are provided opposite to each other with the optical gain medium (4) inserted therebetween, thereby forming a laser light source (13). The other one optical reflection member is provided so as to form a light path for feeding laser light emitted from the laser light source (13) back to the laser light source (13).

摘要： A dye laser capable of lasing at a plurality of wavelengths simultaneously, eg three, comprises a corresponding plurality of transparent containers 4, 5, 6 located between a partially-reflecting mirror 1 and a tiltably adjustable retroreflecting diffraction grating 2 with the containers transversely staggered. The staggered ends of the containers are irradiated by a shallow beam 9 from a pumping laser 7 and contain separate dye solutions whereof the emis-. sion spectra increase in wavelength nearest the pumping laser. There are thus formed three parallel cavities which can lase simultaneously, tuned by the grating 2 operating in three different diffraction orders.
