    Chapter 2: Safety Class 4 lasers such as the Tiberius may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces.

  • Page 8: Chapter 3 Description

    3.1. Introduction The Tiberius laser is a soft aperture, Kerr-lens mode locked (KLM) Ti:Sapphire laser capable of producing widely tunable, high-power femtosecond laser pulses, designed for industrial and scientific research. The Ti:Sapphire oscillator and the pump laser are fully integrated into a temperature-stabilized, sealed, and purged housing. A patented fast-tuning mechanism (Patent # 9,871,340) allows the Tiberius to achieve an industry-leading tuning speed of up to 4000 nm/s.

    17 °C – 25 °C, and should not change by more than 3 °C over a 24-hour period. 3.3.2. Air Quality and Humidity Some optical components in the Tiberius Laser Head are not hermetically sealed. In particular, the window at the output aperture is directly exposed to the room environment. In addition, small amounts of contamination and moisture can penetrate the sealed the cavity.

  • Page 14: Chapter 5 Setup And Operation

    Before operating the laser, check the coolant lines between the chiller and the Tiberius laser head. Power on the chiller and verify that the coolant is running and that there are no leaks. Then power on the Tiberius Controller and the Pump Laser Controller. In addition, verify the PACU is running at about 2.5 L/min.

    You must change the IP address of your host computer’s network interface card to a compatible address in the address space of the Ethernet device you want to connect. For example, The Tiberius controller has a default communication mode for web-setup that uses IP address 172.16.1.1 with a subnet mask of 255.255.0.0. To communicate with the controller, set the host PCs wired Ethernet interface to a similar address like 172.16.1.2...
