Abstract: A master oscillator configured as a seed laser for a laser optical module includes a reduced size, temperature controlled non-planar ring oscillator, a piezo-electric transducer mounted on the non-planar ring oscillator, a pump laser diode, and coupling optics configured to couple a laser output of the pump laser diode to an end face of the non-planar ring oscillator. The pump laser diode may operate as a single-mode pump.

Abstract: Coating-less nonplanar ring oscillator lasers are disclosed. Such lasers may eliminate the need for thin-film optical coatings from a laser cavity, solving the problem of optical damage to the coatings, and thus, providing a longer useful lifetime for the laser for space or terrestrial applications. Such lasers may be compact, ultra-stable, and highly reliable, enabling a low phase noise, single frequency laser in a compact package. Such lasers may be used in CW and/or in pulse mode.

Abstract: High power, low degree of polarization superluminescent diodes (SLDS) are described. A semiconductor optical amplifier (SOA) which amplifies light in substantially one polarizaton state can be used to create a SLD by combining the output from both sides of this polarization sensitive SOA in a manner which results in a depolarized output.
