Mephisto Lasers超窄线宽激光器

名称: Mephisto Lasers超窄线宽激光器

型号: Mephisto Lasers

品牌: Coherent

  • 详细信息

Coherent's portfolio of ultra-narrow linewidth CW lasers are ideal for scientific and instrumentation applications.

Mephisto is a family of solid-state lasers emitting up to 55W CW at 1064 nm, with other wavelengths and pulsed operation available. These lasers exhibit optical properties unmatched by any other product, such as an output tunable over 30 GHz and with the extraordinarily narrow linewidth of about 1 kHz. Extremely low noise (-140 dB/Hz RIN) is another unique characteristic of these lasers.

The Mephisto family is based on the widely recognized original Mephisto design featuring a monolithic Nd:YAG crystal NPRO (Non-Planar Ring Oscillator). This diode–pumped monolithic device is extremely compact, impervious to contamination and other degradation processes, simple to stabilize in temperature and easy to fine-tune by using a PZT. Mephisto is available at power levels up to 2W at 1064 nm and .5W at 1319 nm.


The Mephisto platform has been expanded over time to include:
?High-power amplified versions at 1064 nm (Mephisto MOPA)
?SHG versions at 532 nm (Prometheus)
?Q-switched time bandwidth-limited versions at 1064 nm (Mephisto Q)
?A complete stabilized unit that integrates a I2 reference cell and stabilization electronics (Iodine Frequency Stabilization)


Excellent laser beam parameters, unmatched combination of ultra-narrow-linewidth, frequency tuning, high power and extremely low noise make the Mephisto family the laser of choice for sophisticated scientific applications like atom cooling and trapping, optical metrology, quantum optics, gravitational wave studies and other applications requiring extremely narrow linewidth and ultra-stable laser beams.
