MEPHISTO Q – PRODUCT LINE
Single-frequency pulsed laser • Low noise • 1064 nm • up to 500 mW
APPLICATIONS
- Laser-based metrology (precision spectroscopy, velocimetry, optical ranging & time domain measurements)
- Ultra precision micromachining
- Nonlinear optics pump source (SHG, FHG, DFG)
- General laboratory source
GENERAL FEATURES
- All solid-state, diode-pumped system
- Q-switched operation with CR4+: YAG saturable absorber crystal
- Diffusion-bonded, quasi-monolithic cavity for ultrastable emission
- Nonplanar ring geometry for reliable single-frequency operation
- Low noise control electronics
- - Frequency & power modulation inputs
- - Safety circuitry (soft-start, interlock, temperature guard)
1) Arbitrary units
