    Abstract: A surface-emitting laser may be coupled to a waveguide that includes a Bragg grating that acts as an external cavity. The surface-emitting laser may be attached using surface mount techniques to the chip containing waveguides. The light of the laser can be coupled into the waveguide using an angled reflector. The Bragg reflector in the waveguide serves to stabilize the wavelength and to increase the power of the laser. Such integrated surface emitting laser can be used as a pump laser for a waveguide optical amplifier.

    Abstract: An slab CO2 laser includes spaced-apart elongated slab electrodes. A lasing gas fills a discharge gap between the electrodes. An RF power supply is connected across the electrodes and sustains an electrical discharge in the lasing gas in the discharge gap. Either one or two ceramic inserts occupy a portion of width of the electrodes and in contact with the electrodes. A discharge gap is formed between the portions of the width of the electrodes not occupied by the insert or inserts. Provision of the ceramic insert or inserts increases the resistance-capacitance (RC) time constant of the electrode impedance by increasing the capacitive component of the time constant. This hinders the formation of arcs in the discharge, which, in turn enables the inventive laser to operate with higher excitation power or higher lasing-gas pressure than would be possible without the dielectric insert. The ceramic insert also decreases the difference in impedance of the electrodes with and without a discharge. This leads to a better-behaved discharge, and a discharge that is easier to light.

    Abstract: Plate springs as coupling members can absorb deformation of an oscillator case due to heat and do not transmit the deformation to two optical bases constituting an optical resonator, and it is thereby possible to maintain an appropriate positional relation between the optical cases. A harmful deformation force is produced due to imperfect alignment deformation of bellows each of which is connected between the oscillator case and each optical base. The plate springs can also suppress the force acting on the two optical bases, and it is thereby possible to keep a laser optical axis of a laser beam to be a fixed position.
