Partially end-pumped Nd:YAG slab laser with a hybrid resonator

Abstract

A Nd:YAG slab is partially end pumped by a diode laser stack with three diode laser bars. The pumped volume has a rectangular cross section. A hybrid resonator, which is stable in the plane of small dimension and is off-axis unstable in the plane of large dimension of the gain cross section, was used to yield highly efficient laser operation at diffraction-limited beam quality. The laser design and experimental results are reported.

High-energy picosecond Nd:YVO4 slab amplifier for OPCPA pumping

“…We adopt the InnoSlab concept [9,10] for amplifying energetic picosecond pulses at 50-100 kHz repetition rates from a picosecond seed laser. This concept has been proven for the amplification of low-peak-power lasers without deteriorating beam quality and noise performance [9].…”

The ISOLDE RILIS pump laser upgrade and the LARIS Laboratory

“…The greatest constraint was the need for high output power (80 W at 532 nm), high repetition rate (10 kHz) and short pulse length (<15 ns): a combination atypical of commercially available Nd:YAG lasers which often have pulse lengths in excess of 100 ns. The INNOSLAB concept [5] developed by EdgeWave addresses this by using an end-pumped YAG slab within a small resonator cavity. The EdgeWave laser was ordered in July 2007, installed alongside the CVL system and tested during the 2007/2008 ISOLDE off-line period.…”

Near-diffraction-limited diode end-pumped 2 µm Tm:YAG Innoslab laser

“…LD partially end pumped slab lasers with a hybrid resona tor design (InnoSlab laser) have been proved to be a promising approach to generate a laser with both high power and high beam quality [10]. The InnoSlab laser combines a rectangu lar shaped slab laser crystal, line shaped LD pumping in the central portion of the slab, specially designed thermal manag ing scheme with quasi one dimensional heat conduction and a hybrid resonator configuration.…”
