Event Details

Presenter: Esteban Carbajal, Sr. Product Manager, Zemax, United States

Description: Join Zemax Product Manager, Esteban Carbajal, as he highlights the power of the new OpticStudio STAR module and how it integrates into the Zemax suite for end-to-end optical product development. This talk will cover how complex thermal and structural effects can be understood in high-power laser systems and how Zemax tools empower intelligent design decisions and streamlined workflows:

Easily build STOP analysis into your optical design workflows. Get fast, accurate STOP results with confidence. Analyze the impact of structural and thermal loads on your optical designs with the OpticStudio Structural, Thermal, Analysis and Results (STAR) module. Extend OpticStudio’s capabilities to include structural, thermal, and optical performance (STOP) analysis based on finite element analysis (FEA) datasets. Reduce human error and wasted time spent aligning coordinate systems with visualizations and analyses that bring STOP analysis and OpticStudio into an integrated workflow.

• Import FEA data from any FEA package

• Perform numeric fitting with one-click

• Assess performance impact

Technology Showcase: Improving USP Laser Reliability Through the Innovative Approach to Laser Cooling

Event Details

Presenter: Aldas Juronis, OEM Lasers Program Manager, EKSPLA, Lithuania

Description: FemtoLux 30 is the new femtosecond laser which employs an innovative cooling system and sets new reliability standards among industrial femtosecond lasers. 

Other lasers of similar optical power use water for cooling, which means an additional bulky and heavy water chiller is needed. The chiller requires periodical maintenance. Moreover, in the unfortunate event of water leakage other equipment could be damaged. Instead of using water for transferring heat from a laser head, the FemtoLux 30 uses an innovative Direct Refrigerant Cooling method. 

Refrigerant agent circulates from a compressor and condenser, that are integrated together with the PSU, to a cooling plate via armored flexible lines. The cooling plate is detachable from the laser head for more convenient laser installation.

The FemtoLux 30 femtosecond laser has a tunable pulse duration from <350 fs to 1 ps and can operate in a broad AOM controlled range of pulse repetition rates from a single shot to 4 MHz. 
Maximum pulse energy is more than 90µJ operating with single pulses, but could be as high as 250µJ, while operating in a burst mode.

Event Details

The global management consulting firm McKinsey & Company recently released a report showing that there is a 20% deficit in the job market for job candidates who can do two things - research, and analysis. These two transferable skills are key skill that all PhDs have regardless of their background and makes them highly valuable job candidates, especially in times of uncertainty. In this webinar, we will detail the top 10 transferable skills that PhDs need to communicate on their resume and during their job search as a while, as well as the 3 categories of core competencies that PhDs must master and leverage in order to get hired in industry.
