The laser light source for optical Coherence tomography provided with the integral-type clock

Title:

The laser light source for optical Coherence tomography provided with the integral-type clock

Document Type and Number:

Japanese Patent JP5934270

Kind Code:

B2

Abstract:

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.
