Passive intrinsic-linewidth narrowing of ultraviolet extended-cavity diode laser by weak optical feedback
We present a simple method for narrowing the intrinsic Lorentzian linewidth of a commercial ultraviolet grating extended-cavity diode laser (TOPTICA DL Pro) using weak optical feedback from a long external cavity. We achieve a suppression in frequency noise spectral density of 20 dB measured at freq...
