摘要: A tunable external-cavity Littrow diode laser, with an intracavity electro-optical crystal, which combines a large mode-hop-free tuning range high speeds and accuracy, has been designed. single-mode of 50 GHz at 793 nm output power 60 mW 1.5 GHz/micros is demonstrated. The instantaneous linewidth smaller than 300 kHz. Generally obtained when the elongation cavity proportional to length measured anywhere across beam. This achieved crystal in thickness, thus electric field inside it, varies
