SEMICONDUCTOR LASER DEVICE AND APPARATUS USING NON-LINEAR OPTICAL EFFECT |
摘要 |
Provided is a semiconductor laser device which can generate an ultra-short pulse light. A semiconductor laser device disclosed herein includes a semiconductor laser unit that performs a gain-switching operation using a relaxation oscillation mechanism to generate a first pulse and a following component of the first pulse, and a filter that processes an output from the semiconductor laser unit by removing a signal in a wavelength bandwidth generated due to at least the following portion in a wavelength bandwidth broadened by chirping. The filter is configured as a short pass filter which passes a short-wavelength component. Further, an apparatus using non-linear optical effect which uses the semiconductor laser device is also provided. |

1. A semiconductor laser device comprising:
a semiconductor laser unit that performs a gain-switching operation using a relaxation oscillation mechanism to generate an optical pulse signal which includes a first pulse and a following component of the first pulse; and a filter that processes an output from the semiconductor laser unit by removing a signal in a wavelength bandwidth generated due to at least the following portion in a wavelength bandwidth broadened by chirping, and extracting a component caused by the first pulse to obtain an ultra-short pulse, wherein the filter is a short pass filter which includes an edge filter and passes a short-wavelength component. |
