Daylight Solutions TLS -41000-MHF Enhanced Stability CW-Mode Hope-Free Mid-IR Laser

The ultimate tool for high-resolution spectroscopy and sensor development

Daylight Solutions

Daylight Solutions is proud to introduce the TLS-41000-MHF, a new generation of mode hop-free (MHF) lasers. A complete redesign based on Finite Element Analysis (FEA) maximizes the lasers robustness with respect to vibrations and acoustic perturbations. A factor of 5 linewidth reduction (now <10MHz over a 1s integration time) over our previous model and maximum stability are combined with new modulation capabilities to provide the ultimate tool for high-resolution spectroscopy and sensor development.

Features:

  • Wavelengths offered: 4.0, 4.3, 4.4, 4.5, 4.6, 4.9, 5.3, 6.1, 7.8, 9.5, 10.5µm
  • Mode-Hop-Free tuning range: 60cm-1 typical, ≥30cm-1 guaranteed
  • CW output power: >70mW typical
  • Wavelength accuracy: ±0.5cm-1 (±15GHz), unidirectional
  • Linewidth as low as 5MHz (over 100ms)
  • Improved PZT modulation bandwidth: 0-600Hz
  • Improved current modulation bandwidth: 200Hz – 1MHz
  • Highly collimated beam Controller includes TEC and laser driver Room temperature operation with only a water chiller

Their highest-performing tunable external cavity laser, the CW-MHF series provides continuous tuning in the mid-IR. The combination of a narrow linewidth and excellent wavelength control allows for highly resolved spectral features in both survey and short, high-resolution scans. Two options for wavelength modulation are standard on the TLS-41000-MHF series: piezoelectric (PZT) for low bandwidth (DC to 600Hz) and current modulation for high bandwidth (200Hz to 1MHz). Both systems have been improved, increasing and overlapping their response bandwidths
