Description:
A diode laser pumped resonant cavity is offered which includes a frequency doubler crystal for frequency doubling. The resonant cavity is pumpled via a tunable diode laser. Depending on the required SHG power, the tunable diode laser is either a high power external cavity laser system, or a two stage Master Oscillator Power Amplifier (MOPA) System. The covered wavelength regime ranges from 365nm up to 540nm. Special features are:

High Optical Power

up to 500mW at 480nm available
system suitable for Fourth Harmonic Generation into the deep UV regime

Narrow linewidth

linewidth < 1MHz
excellent side mode suppression > 50dB

Excellent Cavity Design

Bow-Tie type of resonant doubling cavity
Sacher Littrow or Sacher Littman Metcalf type of master lasers
large mode-hop free tuning range of up to 30GHz

Locking Schemes

Hänsch Couillaud type of Locking of the resonant doubling cavity to the pump laser
pump laser can be stabilized to atomic references via Side of Fringe or Pound Drever Hall
