A laser amplifier includes a laser active slab with a source of pump power to amplify an input laser beam, the laser active slab including a block of laser active material having opposed lateral faces defining a wedge lateral dihedral angle, opposed longitudinal faces, and opposed parallel transverse faces, the wedge lateral dihedral angle specified to minimize parasitic amplified spontaneous emission. The source of pump power may be one or more laser diode bars and microlenses producing a gain sheet in the laser active slab. The lateral faces may include optical coatings highly transmitting at a wavelength of the pump power and highly reflecting at a lasing wavelength to provide a folded path for the input laser beam though the gain sheet. The laser amplifier may optionally include one or more external mirrors highly reflecting at the lasing wavelength positioned and oriented to provide one or more additional zig-zag passes through the gain sheet for the input laser beam and to provide a multi-pass-amplified laser beam.

A scope cleaning apparatus and method including a device containing a cleansing solution. An actuating mechanism is provided for passing the solution through flexible tubing coupled to a scope cleaning device. The scope cleaning device includes an elongate sleeve adapted for positioning over and in general coaxial and concentric alignment with the elongate body of the scope or as a parallel tube. The proximal end of the sleeve includes a coupler for detachably coupling to the scope adjacent the eye piece thereof, with the distal end of the sleeve having an aperture therein, with the length of the sleeve being sufficient for termination of the distal end in proximate relation to the lens of the scope. The coupler includes provision for attachment to the solution delivery tubing for enabling passage of the solution into a single fluid passage, which may be annular or parallel, defined between the scope body and the cleaner sleeve. The syringe is actuated through irrigation and aspiration cycles for passage of solution out of, and into, the annular fluid flow path, with the duration of the irrigation cycle preferably being greater than the aspiration cycle.

A laser imaging system with reduced speckle is disclosed. The laser imaging system includes spatially superpositioned 1-D arrays or alternatively 2-D arrays of independent emitters of laser radiation, with each emitter having a spectral bandwidth Δλcentered at some arbitrary wavelength λ. The elements of the array are allowed, by design, to have a slightly different central wavelength, thereby creating an ensemble bandwidth ΔΛ which is much greater than the bandwidth Δλof any individual emitter in the array. The resulting increased bandwidth reduces speckle in a displayed image.
