Abstract :
A Tm:YALO laser end-pumped by a 794-nm laser diode array is reported. The output power is 1.2 watts when the quasi-cw diode array is operated at a 50 Hz repetition rate (5% duty cycle). The Tm:YALO laser operates at 1.94μm with an output coupling of 2.5%, and at 1.945μm and 1.99μm simultaneously with an output coupling of 2.0%. The dependence of laser wavelength on output coupling is consistent with a previously reported Tm:YALO laser pumped by a Ti:sapphire laser
