Patent CA-2316004-A1 (CA)
Inventor: HORVATH CHRISTOPHER
IPC: H01S3/081
Filed: 2000-08-15
Abstract: An oscillator for isolating a transverse electro-magnetic (TEM) zero-zero mode pulsed laser beam includes a laser pumping diode that is mounted on a base to induce a multi-mode laser beam from a lasing medium. As initially induced, the multi-mode laser beam is directed along a path and is characterized by a beating signal which has a frequency that is based on amplitude variations of laser pulses in the multi-mode laser beam. Electronics detect this beating signal and generates a responsive error signal. With closed loop control, the error signal is used to advance a straightedge toward the path of the multi-mode laser beam to remove transverse modes from the multi-mode laser beam with the straightedge. This advancement continues until the error signal is a null and the zero-zero mode pulsed laser beam is thereby isolated.
