TY  - JOUR
AB  - We report the first experimental demonstration of a wavelength tunable passively Q-switched red-diode-endpumped Alexandrite laser using a semiconductor saturable absorber mirror (SESAM). We present the results ofthe study of passive SESAM Q-switching and wavelength-tuning in continuous diode-pumped Alexandritelasers in both linear cavity and X-cavity configurations. In the linear cavity configuration, pulsed operation upto 27 kHz repetition rate in fundamental TEM00 mode was achieved and maximum average power was 41 mW.The shortest pulse generated was 550 ns (FWHM) and the Q-switched wavelength tuning band spanned wasbetween 740 nm and 755 nm. In the X-cavity configuration, a higher average power up to 73 mW, and obtainedwith higher pulse energy 6.5 J at 11.2 kHz repetition rate, in fundamental TEM00 mode with excellent spatialquality M2 < 1.1. The Q-switched wavelength tuning band spanned was between 775 nm and 781 nm.
