Abstract : A standard cavity, Q switched laser is used to initiate and sustain submicrosecond pulses in a long laser. Short pulses from the standard cavity laser are directed onto the remote reflector of a long laser and are then reflected back through the lasing material of the long laser. Properly timed activation of the long laser lasing material causes amplification and oscillation of the pulses in the long laser cavity. Beam expanding telescopes are used to focus the laser pulses on the long laser's remote reflector. By way of a specific example, the generation of submicrosecond pulses in a long laser has been accomplished using neodymium doped yttrium aluminum garnet (Nd:YAG) as the lasing material perating at 1.06 micrometers.
