High speed liquid jet from the nozzle of one closed vessel can be formed, which is urged by vaporization effect induced by fiber-transmitting infrared pulse lasers. The signals of water-jet pressure and shock wave pressure under various laser parameters and stand-off distances (d: distance between the end of optical fiber and the nozzle exit) are detected by two polyvinylidene fluoride (PVDF) needle hydrophones and are recorded by one oscilloscope. The relationship between water-jet pressure, shock wave pressure and pulse duration, laser energy is analyzed. The experimental result indicates that there is a positive correlation between water-jet pressure and pulse duration (494~967 μs) when the laser energy is 426.3 mJ. Contrarily, the relationship between shock wave pressure and pulse duration is negative when d is 2 cm or 4 cm. However, for d=6 cm the shock wave pressure increases firstly and decreases afterwards, and reaches a maximum value of 1.32 MPa when the pulse duration is 736 μs. Both water jet pressure and shock wave pressure increase in proportion to pulse energy (266.3~420.8 mJ) when the pulse duration is 480 μs. When the laser parameters are invariable, jet pressure and shock wave pressure all increase with increase of d.
