), so the emission bandwidth is far narrower, usually by using a linewidth in the megahertz region. Further more linewidth narrowing is feasible with external cavities and significantly with narrowband optical comments from a reference cavity (→ frequency-stabilized lasersการทำเลเซอร์ diode นั้นไม่เจ็�
