Compact Pulsed Nd:YAG Lasers

Del Mar Photonics offers compact pulse Nd:YAG lasers with excellent beam quality, high energy/efficiency and possibility of efficient PRR changes with no significant degradation of the output beam parameters. No matter how you may wish to use it — as a stand­alone laser or as a pump source for tunable lasers and OPO — the Del Mar Photonics LQ529 laser provides a combination of high operation parameters, reliability and reasonable price which could not be achieved earlier.

Ring cavity design of the LQ529 oscillator ensures perfect balance of energy, beam quality and reliability.

Excellent Beam Quality
Compensation of depolarization over the Nd:YAG rod cross­section together with traditional advantages of ring cavities ensure excellent beam profile. Unique optical design of the LQ529 not only makes losses and distortions caused by induced birefringence almost negligible, but also minimizes thermal lensing effect. The above allows the user to vary pulse repetition rate within a wide range and requires no further cavity alignment to preserve high beam quality and output energy.

This constitutes a great advantage over lasers using expensive and difficult to align Gaussian optics and thus demanding realignment and sometimes even replacement of optical components in order to avoid dramatic worsening of their output parameters if pulse repetition rate (PRR) has been changed.

Energy Through Efficiency
One of the main reasons for moderate efficiency of conventional Q-switched lasers is birefringence induced in the Nd:YAG rod leading to depolarization of laser output. Each time the beam passes through the cavity, depolarized lasing is filtered by various polarization units and is dropped out of the cavity that leads to decrease in laser operation efficiency. Optical design of the LQ529 laser cavity allows to practically eliminate energy losses caused by depolarization and provides laser energy output with more than 2% wall-plug efficiency of a laser system (total electrical-to-optical power efficiency). Such a high efficiency allows the LQ529 to provide up to 600mJ output energy without using an amplifier. Single rod and single flash lamp design is the determining factor for reduction of the laser price and maintenance costs.

A power supply unit and a self-contained water-to-air cooling system are integrated into one compact package. Remote controller with the tactile panel and large LCD makes laser operating much more convenient.

Stable And Reliable Operation
One of the obvious advantages of the laser is its absolute mechanical stability and rigidity.

All optical components are mounted on the rigid optical bench which is mechanically and thermally isolated from the laser housing. This ensures exceptional alignment stability even under toughest conditions of transportation and operation. All non­linear crystals and Pockels cell are temperature stabilized. Optical bench with cavity components is also temperature­stabilized. High-precision termo­stabilization ensures minimal pulse­to­pulse and long­term instability. Heating of optical components to the temperature exceeding ambient totally eliminates any risk of condensation. This feature along with dust­proof housing protects the optics from damage and minimizes the necessity in service. It should also be noted that the LQ529 laser design eliminates the necessity of any laser alignments after flashlamp replacement, while the replacement procedure itself takes less than 10 minutes.

All Harmonics Available
All harmonic options — 532nm, 355nm, 266nm and 213nm — are available as standard.
High-efficiency Harmonic Generators can be either built-in (except for the FiHG) or supplied as separate units upon the customer’s request. For this reason all the harmonics can be ordered with the laser or at later date.

High­power cooling system and automatic temperature control with 0.5°C precision ensure stable laser operation at up to 30°C ambient temperature. A heater built into the cooling system reduces warm-up time to several minutes even at 15°C ambient temperature.
