摘要： A frequency swept laser source for TEFD-OCT imaging includes an integrated clock subsystem on the optical bench with the laser source. The clock subsystem generates frequency clock signals as the optical signal is tuned over the scan band. Preferably the laser source further includes a cavity extender in its optical cavity between a tunable filter and gain medium to increase an optical distance between the tunable filter and the gain medium in order to control the location of laser intensity pattern noise. The laser also includes a fiber stub that allows for control over the cavity length while also controlling birefringence in the cavity.

摘要： The present invention relates to a switchable dual wavelength solid state laser with a solid state gain medium (1) which is selected to emit optical radiation at a first wavelength with a first polarization and of at least a second wavelength with a second polarization different from said first polarization when optically or electrically pumped. A polarizing device (7) is arranged within the laser cavity, said polarizing device (7) being adjustable at least between said first and said second polarization. The two end mirrors (2, 3) of the laser cavity are designed to allow lasing of the solid state laser at the first wavelength when the polarizing device (7) is adjusted to the first polarization, and to allow lasing of the solid state laser at the second wavelength when the polarizing device (7) is adjusted to the second polarization. The proposed solid state laser allows an easy switching between two emission wavelengths.

摘要： PROBLEM TO BE SOLVED: To provide a pulse high-repeating laser oscillator having stability which employs a thin-plate laser medium having low amplification gain.
SOLUTION: The solid laser oscillator includes at least a pair of laser resonators; a thin-plate laser medium added with an active substance having a high-level lifetime longer than the period of a repeating operation as a laser medium; a thin-plate laser medium provided on at least one reflector in the laser resonator and a Q switch element provided in the resonator; an excitation source for exciting the laser medium; and a control section for driving the Q switch element. The control section causes oscillation when the Q switch element is in the ON-state, and turns off the Q switch during oscillation in which the high-level density of the active substance in the laser medium remains to interrupt the oscillation. When the Q switch is in the ON-state, the high-level excitation density is maintained so that the Q switch pulse can oscillate, and thus, stable high-repeating pulse oscillation can be achieved.
