New high energy and Mhz frequency stabilised laser source with 18 KHz repetition rate for spectroscopy
Résumé
We report a new high energy and frequency stabilised pulsed laser source from the amplification of a single-mode cw dye laser using a new amplifier configuration. The system can be divided into three parts: a commercial frequency stabilised cw dye laser (Coherent Inc.) pumped by an intracavity frequency doubled Nd:YVO/sub 4/ cw laser (VERDI), a single stage multi-pass amplifier based on a vertical free-flowing dye jet, which is pumped by a laboratory-made CuHBr laser.
