Title:
An optical frequency comb stabilized light source and a signal generator
Document Type and Number:
Japanese Patent JP6133236
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to obtain an optical frequency comb having a higher repetition frequency with high precision.SOLUTION: An optical frequency comb stabilization light source makes a stabilization CW light generation unit 103 generate continuous wave light having a frequency different from a second light source stabilized using a first optical frequency comb generated by a low speed optical frequency comb generation unit 101 to compare a second optical frequency comb generated by a high speed optical frequency comb generation unit 102 with continuous wave light generated by the stabilization CW light generation unit 103. Based on this comparison status, a feedback control unit 105 controls a signal generator 113.
