Quadruplers: or 4th harmonic generation units for quatrupling laser frequency in the wavelength range 680-1060nm to 190-265nm. The TP-FHG units have to work with a TP-Tripler to g
enerate the 4th harmonics. The 4th harmonic generation from the TP-FHG unit is sum-frequency processes which mix the third harmonic pulse and the fundamental pulse from a TP-tripler,
W+3W=4W
where W, 3W, and 4W are the fundamental, third harmonic, and fourth harmonic frequency respectively.
Two Models of TP-FHG
| 1 | TPL FHG for laser oscillators. |
| 2 | TPH FHG for laser amplifiers. |
TPL-FHG Specifications:
· Single set of optics for generating UV wavelength from 250nm to 195 nm
· More than 10 mW UV power from 200-225 nm
· For 100KHz Ti:S amplifier and 76 MHz Oscillator
· Compact size 30x16x13 (in cm)
Note: Tests are done with a 100fs pulse width and 80MHz repetition rate Ti:Sapphire oscillator.
