I’m interested in the 3rd harmonic generator for an amplified Ti:sapphire laser. What is the maximum pulse energy? The system is a regenerative amplifier that produces 750 mW at a repetition rate of 100 kHz, which is a pulse energy of 7.5 microjoules in 50 femtoseconds. The beam diameter is 2.7 mm. We have tried to use a Coherent 9300 harmonic system, but it is designed for oscillator energies of nanojoules, so it is too tightly focused on the crystal and generates white light.
Del Mar Photonics:
We can offer about 7-8% efficiency, the version for 8 uJ will be non-standard. Please find enclosed the quotation for the TH generator along with
the drawing. Please note that since the unit is non-standard the dimensions may be extended by +100 mm in length and +50 mm in width.
