Pulses of 100-fsec duration are obtained by synchronous pumping of a colliding-pulse ring dye laser with a mode-locked Ar(+)-ion laser. Stable operation of the synchronously pumped colliding-pulse mode-locked laser over hours was obtained by a suitable choice of the distance between the gain and the absorber in combination with an appropriate pump-pulse sequence.

This manual describes a procedure to align the cavity of our Ti:Sapphire ring laser and its injection with an Argon-Ion pump laser beam. The setup is shown in figure 1. An 8W Argon-Ion pump beam is adjusted in size and degree of divergence by a telescope consisting of a 62mm and an 88mm lens (L1 and L2). A periscope (mirrors P1 and P2) and a collimation lens C (f=175 mm) is used to inject the 5...

Various species of high intensity highly charged state heavy ion beams with small emittance are required in many fields including particle physics, medical uses, inertial fusion, and simulator of space radiations. Direct Plasma Injection Scheme (DPIS), we have developed for several years, is a unique scheme to provide heavy ion beams to meet the above requirements. A high-density plasma created...

Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry is a sensitive and versatile method for biomolecular analysis which has potential for high-throughput screening in many applications. To obtain mass spectra of optimal quality, however, laser fluence is continuously adjusted during data acquisition to be close to the threshold level of ion production, requiring a skilled oper...

Laser driven particle acceleration and measurements ofion energy loss in plasma largely rely on suitable targets toachieve good particle beam and plasma quality. Recent re-search results [2] indicate that cryogenic targets allow forvery high ion energies. Advantages of our cryogenic tar-gets include high purity at solid density in a self-supportedstructure as well as fit...
