Footnotes:

  1. Due to our continuous improvement program, specifications are subject to change without notice.
  2. The Ascend is a Class IV - High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.

Features

Ultra-efficient Cooling

Ascend is based upon proprietary technology that employs an ultra-efficient cooling scheme to provide maximum stability and long-term reliability. When used for pumping a Spectra-Physics amplifier, Ascend is the most reliable, most efficient and lowest noise pump laser available.

Easily Changed Configurations

Ascend configurations can be to maximize the utility of your amplifier system. The Ascend flexibility means you can design experiments anywhere in the 1 to 10 kHz repetition rate range. Ascend is available in >60 W and >40 W output power levels to support your specific amplifier system configuration and requirements.

Industrial Reliability With Leading-edge Performance

Ascend continues Spectra-Physics’ long-standing commitment to producing the highest performing, most reliable diode-pumped solid state lasers. Ascend combines industrial reliability and ruggedness with leading-edge performance to maximize the performance of your Spectra-Physics ultrafast amplifier.
