Picosecond Nd:YLF five-passes laser amplifier with 20 mJ pulse energy

High stability, single frequency, 300 mJ, 130 ps laser pulse generation based on stimulated Brillouin scattering pulse compression

“…Especially in the research of plasma diagnosis and laser ranging, in order to obtain higher spatial resolution (below 5 cm), short pulse width below 150 ps is particularly necessary. Mode-locking is usually applied in the generation of picosecond laser pulses (Su et al, 2012;Ai et al, 2012), but the obtained pulse energy generally ranges from several nanojoules to hundreds of microjoules. To get higher energy lasers with picosecond pulse duration, the regenerative amplifier system has been applied to amplify the mode-locked pulses (Ai et al, 2012).…”

Laser amplification of optical images using a CW Nd:YAG amplifier

“…This can be useful in short distance optical communication, ultra-short pulse amplification and incrementation in the resolution of weak and non-detectable signals in spectroscopic analysis. Several approaches are possible such as single-pass and multiple-pass amplification [1], in regenerative amplifiers and MOPA amplifiers [2], mostly used in femtosecond lasers. High average power up to kilowatts can be achieved by using several lasing modules in a common cavity, during which process sufficient power can be extracted for applications such as laser welding, melting and evaporation of materials.…”

Raman Frequency Conversion of Picosecond Pulses in the YVO4Crystal

“…In our single-pass SRS experiment, a home-made picosecond Nd:YLF laser is used as a pump source. [14] With a 10 × 10 × 11 mm LBO as a frequency doubling crystal, it can produce 5 mJ 526.5 nm green lasers. The output beam is about 2 mm in diameter.…”
